Raspberry Pi industrial applications have expanded steadily since the platform first appeared in engineering toolkits as a low-cost Linux development board. With the arrival of Raspberry Pi 5, that expansion has accelerated. The performance uplift, the first PCIe interface on a full-size Raspberry Pi, the rearchitected I/O silicon, and the growing ecosystem of HAT+ add-on boards - including dedicated AI accelerators - have shifted the Pi 5 from a capable prototyping platform into hardware that engineers are taking seriously for deployed industrial systems. This guide sets out what the Pi 5 offers, what its limitations are in industrial contexts, how it can be extended with the right add-on hardware, and where the Compute Module 5 is the more appropriate choice for production deployment.

Summary

The Raspberry Pi 5 is a 64-bit quad-core Arm Cortex-A76 single-board computer with significantly more processing power than its predecessor, a PCIe 2.0 interface for high-bandwidth peripherals, improved camera and display support, and a real-time clock. For industrial engineers, it is most valuable as a rapid prototyping and development platform, as a cost-effective edge compute node in benign environments, and as the foundation for AI-at-the-edge applications when paired with the AI HAT+ or AI HAT+ 2. For production deployment in harsh environments, the Compute Module 5 on an industrial carrier board remains the more appropriate choice.

What is the Raspberry Pi 5?

Raspberry Pi 5 is the fifth generation of the full-size Raspberry Pi single-board computer, and the first to use silicon designed in-house at Raspberry Pi. It is built around a 64-bit quad-core Arm Cortex-A76 processor running at 2.4GHz - the same CPU architecture as the Compute Module 5 - and is available in four RAM configurations: 2GB, 4GB, 8GB, and 16GB LPDDR4X.

The headline performance figure is a 2–3× increase in CPU performance relative to Raspberry Pi 4, which is significant in absolute terms and even more so in the context of what that headroom enables for edge computing and local data processing. But the specification changes that matter most to industrial engineers go beyond raw CPU speed.

Key specifications for industrial engineers

RP1 Southbridge and I/O Performance

For the first time, a full-size Raspberry Pi uses in-house silicon beyond the main SoC. The RP1 "southbridge" handles the bulk of I/O capability on the Pi 5, and the step change in peripheral performance it delivers is material for industrial use.

• USB bandwidth is more than doubled compared to Pi 4, enabling faster data transfer to external storage, industrial USB peripherals, and UAS drives
• The dedicated two-lane 1Gbps MIPI camera and display interfaces of previous models have been replaced by a pair of four-lane 1.5Gbps MIPI transceivers, tripling total bandwidth and supporting any combination of up to two cameras or displays
• Peak SD card performance is doubled through support for the SDR104 high-speed mode

For engineers building systems that involve camera feeds, industrial displays, or high-speed data ingest from USB peripherals, these are meaningful capability improvements rather than incremental refinements.

PCIe 2.0 x1 interface

The single-lane PCIe 2.0 interface exposed on the Pi 5 is the specification change with the most significant long-term implications for industrial and engineering use. PCIe enables the M.2 HAT+ adapter, which in turn enables NVMe SSD storage and AI accelerator modules to connect to the Pi 5 directly - providing the reliable solid-state storage and on-device inference performance that industrial edge applications increasingly require.

Real-Time Clock with external battery support

The on-board RTC, backed by an external battery connector, allows the Pi 5 to maintain accurate system time through power cycles and periods without network connectivity. For unattended industrial deployments where NTP synchronisation is not always available - remote monitoring nodes, equipment in electrically noisy environments, or deployments on intermittent cellular connectivity - this removes a practical gap that previous Pi models required third-party RTC add-on boards to address.

RAM and memory options

The 2GB variant suits lightweight IoT gateway and data logging applications; 4GB covers the majority of Linux-based industrial applications comfortably; 8GB is the practical choice for machine vision, concurrent process management, or applications running alongside a full desktop environment; 16GB is available for demanding edge AI inference workloads, particularly when running larger models locally. BCD Atlantik stocks the full range, with the 8GB variant the most commonly specified for industrial development work.

Extending Pi 5 for industrial and engineering applications

The HAT+ ecosystem is where the Pi 5's industrial utility expands most significantly. The PCIe interface that underpins the M.2 HAT+ opens up a hardware expansion path that was not available on previous full-size Pi models.

AI acceleration

Three AI accelerator products from Raspberry Pi are available through BCD Atlantik, all compatible with Pi 5 only via the PCIe interface.

The Raspberry Pi AI HAT+ offers 13 or 26 TOPS via a Hailo neural network accelerator, fitted directly to the Pi 5 via its PCIe interface. The 26 TOPS variant supports more complex neural processing and the ability to run multiple concurrent AI models - relevant for applications combining object detection with classification or tracking simultaneously.

The Raspberry Pi AI HAT+ 2 represents a substantial step up: 40 TOPS of INT4 inferencing performance via the Hailo-10H accelerator, with 8GB of dedicated on-board RAM. This dedicated RAM means the AI workload does not compete with the host Pi 5 for system memory, making the AI HAT+ 2 suitable for running large language models and vision-language models locally - enabling offline process control, secure local data analysis, facilities management automation, and advanced robotics applications that would otherwise require cloud connectivity for inference.

Storage expansion

The Raspberry Pi M.2 HAT+ connects M.2 2230 or 2242 format PCIe and NVMe devices to the Pi 5's PCIe connector, providing a path to fast, reliable NVMe SSD storage. The HAT+ specification allows Raspberry Pi OS to automatically detect the HAT+ and connected devices. For industrial applications where booting from an SD card is a reliability concern - and where the write endurance and data integrity guarantees of an industrial NVMe SSD are required - the M.2 HAT+ with an appropriate NVMe drive is the practical solution. BCD Atlantik also supplies SSD kits for Pi 5 with the SSD pre-assembled on the M.2 HAT+ for immediate use.

Power over Ethernet

The Raspberry Pi PoE+ HAT enables the Pi 5 to be powered directly from a PoE+ capable Ethernet switch, eliminating the need for a separate power supply at each deployment point. For distributed sensor networks, building automation nodes, or point-of-sale deployments where running separate power cabling to each device is impractical, PoE+ simplifies both installation and cable management significantly.

Environmental sensing

The Raspberry Pi Sense HAT 2 adds an array of onboard sensors - pressure, humidity, temperature, colour, orientation, and movement - alongside an 8×8 RGB LED matrix and five-button joystick. Originally developed for the International Space Station as part of the Astro Pi programme, it provides a compact, well-supported sensing platform for environmental monitoring, condition monitoring, and data logging applications where a single board can handle both sensing and compute.

Industrial applications of Raspberry Pi 5

• Rapid prototyping and system development: the Pi 5's combination of performance, standard Linux software stack, and accessible GPIO means engineering teams can prototype, validate, and iterate an industrial system design faster than on most proprietary embedded platforms
• Edge AI and machine vision: paired with the AI HAT+ or AI HAT+ 2, the Pi 5 becomes a capable on-device inference platform for quality inspection, anomaly detection, object counting, and camera-based monitoring applications
• Industrial IoT gateways: the Pi 5's networking capability, USB port count, and processing headroom make it well-suited to gateway applications aggregating data from multiple sensors or serial devices and forwarding it to a SCADA system or cloud platform
• HMI development and display systems: the improved MIPI display interface and GPU performance support the development of industrial HMI interfaces, digital signage, and kiosk systems on the standard Raspberry Pi OS desktop stack
• Laboratory and test equipment: data acquisition, instrument control, and automated test systems where the open ecosystem of Python libraries, GPIO access, and USB instrument connectivity makes the Pi 5 an accessible and capable platform
• Smart agriculture and environmental monitoring: distributed sensor nodes in agricultural, environmental, and infrastructure monitoring deployments where cost per node matters and benign operating conditions make standard Pi hardware appropriate

Limitations and considerations for industrial deployment

Engineers evaluating the Pi 5 for industrial use should be clear-eyed about where the standard hardware has constraints relative to purpose-built industrial computing platforms.

Operating temperature

The Raspberry Pi 5 is rated for operation between 0°C and 50°C ambient. Industrial environments regularly exceed this range - particularly in unventilated cabinets in summer, in vehicles, in outdoor enclosures, or in cold storage facilities. Applications in these environments require either active thermal management and an appropriately rated enclosure, or a purpose-built industrial computer such as the Edatec ED-IPC series based on the Compute Module 5, which is rated for -25°C to 60°C and available with optional 4G, isolated serial interfaces, and industrial power input.

Power input

The Pi 5 uses USB-C 5V/5A power delivery. Industrial deployments typically run on 9–36V DC from a DIN-rail power supply; there is no direct wide-voltage input on the standard Pi 5. Step-down converters can address this, but add board space and component count that an industrial carrier board design around the CM5 eliminates by design.

Storage reliability

Booting from an SD card remains the default for the Pi 5, and SD card reliability under continuous write workloads is a known concern for always-on deployments. The M.2 HAT+ with an industrial NVMe SSD resolves this, but adds cost and a HAT that must be accommodated in the physical design. For production deployments, this should be treated as a default rather than an optional upgrade.

Enclosure and mounting

The Pi 5 is a bare single-board computer; industrial deployment requires an appropriate enclosure, DIN-rail or panel mounting, and consideration of dust and moisture ingress. This is engineering effort that a purpose-built industrial carrier board or packaged computer eliminates.

Raspberry Pi 5 vs Compute Module 5: Choosing the right form factor

The same Raspberry Pi OS software stack runs on both platforms, which is the key practical advantage of this ecosystem: code developed and validated on a Pi 5 transfers directly to a CM5-based industrial carrier without a software bring-up process. This means the Pi 5 is the natural development and validation platform for applications that will ultimately be deployed on CM5-based hardware.

Best practices for Pi 5 in industrial and engineering projects

1. Replace SD card boot with NVMe from the start. For any deployment writing data continuously - logging, monitoring, vision systems - use the M.2 HAT+ with an industrial NVMe SSD as the default storage. SD card failure is the most common cause of unexpected Pi downtime in deployed systems.
2. Size RAM to the workload, not to the minimum. The cost difference between 4GB and 8GB is modest; the cost of an application running out of headroom in a deployed system is not. For anything involving concurrent processes or AI inference, specify 8GB as a baseline.
3. Match the AI accelerator to the inference requirement before specifying. The AI HAT+ (13 or 26 TOPS) suits single-model and concurrent vision tasks; the AI HAT+ 2 (40 TOPS, 8GB RAM) suits generative AI and vision-language model inference. Each has a distinct use case; choosing the wrong tier either under-specifies the application or adds unnecessary cost.
4. Validate thermal performance in the target enclosure, not on an open bench. The Pi 5 with an AI HAT+ under load generates meaningful heat; confirm that the Active Cooler is sufficient in the intended enclosure before committing to a physical design, particularly if convection cooling is limited.
5. Plan the transition to CM5 for production volume. If a project is likely to move from a handful of Pi 5 development units to production volume in an enclosure, plan the carrier board design early. The software is the same; the time cost is in the hardware design, not the OS bring-up.
6. Use the RTC battery connector from day one. Populating the RTC battery connector costs almost nothing and eliminates a class of time-synchronisation problems that affect unattended deployments, particularly those on intermittent network connectivity.

Frequently asked questions

Is the Raspberry Pi 5 suitable for 24/7 industrial deployment?

For deployments in controlled environments within its 0–50°C operating range, with NVMe storage rather than SD card, the Pi 5 can run continuously and reliably. For demanding environmental conditions - wider temperature ranges, DIN-rail cabinet installation, vehicle use - the Compute Module 5 on an industrial carrier board such as the Edatec ED-IPC series is the more appropriate platform.

What does the PCIe interface on Pi 5 enable that previous models couldn't do?

PCIe enables direct connection of NVMe SSDs (via the M.2 HAT+) and AI accelerator modules (AI HAT+ and AI HAT+ 2). Neither category of peripheral was directly connectable to previous full-size Pi models without workarounds. Both are significant for industrial and engineering applications.

Can the Raspberry Pi AI HAT+ 2 run LLMs locally?

Yes. The AI HAT+ 2's Hailo-10H accelerator and 8GB of dedicated on-board RAM are designed for running selected large language models and vision-language models locally on Raspberry Pi 5, without cloud connectivity. This enables offline process control, secure local data analysis, and conversational AI interfaces in air-gapped or connectivity-limited environments.

Does Raspberry Pi 5 support Power over Ethernet natively?

Not natively - PoE+ support requires the Raspberry Pi PoE+ HAT, which sits on the 40-pin GPIO header and draws power from the Ethernet port on a PoE+ capable switch. This is a well-supported configuration and removes the need for a separate USB-C power supply at each Pi 5 deployment point.

How does the Pi 5's MIPI camera support compare to previous generations?

Pi 5 replaces the dual two-lane 1Gbps MIPI interfaces of previous models with a pair of four-lane 1.5Gbps MIPI transceivers - tripling total bandwidth - and supporting any combination of up to two cameras or displays. Combined with the rearchitected Raspberry Pi Image Signal Processor, this makes Pi 5 significantly more capable for machine vision, multi-camera, and high-resolution display applications than its predecessors.

Can I use the same software on Pi 5 and CM5?

Yes. Both run the same Raspberry Pi OS on the same Arm Cortex-A76 architecture. Code, libraries, and application software developed on a Pi 5 will run on a CM5-based carrier board without modification, which makes the Pi 5 the natural development platform for systems that will be deployed on industrial CM5 hardware at production volume.

Is the Raspberry Pi 5 appropriate for safety-critical industrial applications?

The Raspberry Pi 5 and its software stack are not certified for functional safety applications (IEC 61508, ISO 26262, IEC 62061 etc.). For applications where failure could result in harm to people or equipment and where functional safety certification is a requirement, a certified industrial controller platform should be used. The Pi 5 is well-suited to monitoring, analytics, visualisation, and non-safety-critical control applications.

Key takeaways

• Raspberry Pi 5 delivers a 2–3× CPU performance uplift over Pi 4 on the same Arm Cortex-A76 architecture as the Compute Module 5, making the two platforms fully software-compatible
• The PCIe 2.0 interface is the most significant new capability for industrial engineers, enabling NVMe storage and AI accelerator add-on boards that were not possible on previous full-size Pi models
• The AI HAT+ (13 or 26 TOPS) and AI HAT+ 2 (40 TOPS, 8GB RAM, LLM/VLM capable) provide a tiered path to on-device AI inference suited to different application complexity levels
• The Pi 5 is best suited to prototyping, development, and controlled-environment deployment; the Compute Module 5 on an industrial carrier remains the right choice for production deployment in harsh environments
• Replacing SD card boot with NVMe SSD via the M.2 HAT+ is the single most important reliability improvement for any Pi 5 deployed in an always-on industrial context
• Software developed on Pi 5 transfers directly to CM5-based industrial hardware - making Pi 5 the natural development platform for the industrial embedded pipeline

Conclusion

Raspberry Pi 5 has arrived at a point where the platform's capabilities genuinely close the gap with dedicated industrial single-board computers for a broad range of engineering and industrial applications - not just in processing power, but in the I/O performance, storage options, and AI acceleration ecosystem that industrial deployments require. The addition of PCIe, the improved camera interfaces, and the HAT+ AI accelerator range have changed the nature of the conversation from "can the Pi do this?" to "at what scale and in what environment should it be doing this?"

For engineers building prototypes, developing edge AI applications, deploying low-volume systems in controlled environments, or validating software before a CM5-based production run, the Pi 5 is a more capable platform than any previous generation. Understanding where its limitations lie - and when the step to an industrial CM5 carrier board is warranted - is the practical knowledge this guide aims to provide.

Raspberry Pi Compute Module business use has grown significantly over the past few years, moving well beyond education and hobbyist prototyping into serious commercial product development. Manufacturers, system integrators, and engineering teams across sectors from healthcare to industrial automation are now designing the Raspberry Pi Compute Module into products they intend to ship in volume. The reason is straightforward: the Compute Module takes the processing power, software ecosystem, and community support of the Raspberry Pi platform and repackages it into a compact, integration-ready form that suits custom hardware design rather than off-the-shelf development boards.

This guide explains what the Raspberry Pi Compute Module is, why it has become a credible choice for embedded systems in a business context, and how to decide which variant fits your application.

Summary

The Raspberry Pi Compute Module is a system-on-module (SOM) that combines the processor, RAM, and optional eMMC storage of a Raspberry Pi onto a compact board designed to plug into a custom carrier board rather than be used standalone. For businesses, it offers a well-supported, cost-effective platform for building embedded products in volume, with the advantage of a mature Linux software stack, long-term supply commitments, and a large developer community. The CM4 and CM5 are the two current generations, differing primarily in processing power, I/O capability, and target application profile.

What is a Raspberry Pi Compute Module?

A Raspberry Pi Compute Module is a small form-factor system-on-module that packages the core components of a Raspberry Pi (processor, memory, and storage) onto a board designed for integration rather than direct use. Unlike the standard Raspberry Pi single-board computers, a Compute Module has no USB ports, no full-size HDMI output, and no GPIO headers in the traditional sense. Instead, it exposes its interfaces through a high-density connector, allowing an engineer to design a custom carrier board that breaks out only the interfaces the product actually needs.

This distinction matters commercially. A standard Raspberry Pi is designed as a general-purpose development board; a Compute Module is designed to become a component inside something else. That shift in intent changes what becomes possible in terms of product form factor, interface selection, environmental ruggedisation, and BOM optimisation.

How it works in an embedded product

In a typical embedded deployment, the Compute Module sits on a custom-designed carrier board developed by the product manufacturer. The carrier board provides the connectors, power management, peripherals, and industrial interfaces relevant to that specific product; whether that is a touchscreen interface, RS485 for machine communication, a cellular modem, or an array of digital I/O lines for control applications.

During development, teams commonly use an official IO board, such as the Raspberry Pi CM4 IO Board or the Raspberry Pi CM5 IO Board, to prototype and validate their software before committing to a custom PCB design. Once the software stack is stable and the hardware requirements are confirmed, the carrier board can be designed to exactly match the product's needs, removing any unnecessary components and reducing unit cost accordingly.

The Raspberry Pi OS and its ecosystem of libraries, drivers, and community tooling transfer directly from the development environment to production, significantly reducing the software bring-up time compared to platforms with less established support.

Key features and specifications

Raspberry Pi CM4

The Compute Module 4 is built around a quad-core ARM Cortex-A72 processor running at 1.5GHz, with up to 8GB of LPDDR4 RAM and optional eMMC storage in 8GB, 16GB, or 32GB capacities. It supports dual 4K display output, hardware video decode at up to 4Kp60, Gigabit Ethernet, USB 2.0, dual camera interfaces, and a PCIe Gen 2 x1 interface for expansion. Wireless variants include dual-band 2.4/5GHz Wi-Fi and Bluetooth 5.0 with modular compliance certification, reducing the regulatory overhead of adding wireless connectivity to a product.

Available in a number of variants covering different combinations of RAM, storage, and wireless, the CM4 gives engineering teams flexibility to match the module specification tightly to the application, avoiding the need to pay for memory or storage that the product does not require. Extended temperature variants rated from -40°C to +85°C are also available through BCD Atlantik, making the CM4 suitable for demanding environmental conditions.

Raspberry Pi CM5

The Raspberry Pi Compute Module 5 represents a significant step up in performance. Built on the same quad-core Arm Cortex-A76 architecture as the Raspberry Pi 5, it delivers noticeably higher compute throughput and improved I/O capabilities compared to the CM4. RAM options extend to 16GB, and eMMC storage is available from 0GB Lite up to 64GB. Dual 4Kp60 HDMI output, Gigabit Ethernet, and the option of a fully-certified wireless module round out the specification.

The CM5 is the right choice where the application needs more compute headroom, such as handling multiple data streams, running edge inference workloads, or driving high-resolution display content alongside background processing tasks. For teams starting a new design today, the CM5 offers a longer effective product life before compute becomes a constraint.

Benefits of using Raspberry Pi Compute Modules for business applications

• Established ecosystem: The Raspberry Pi software stack, community, and library support are among the most mature of any embedded Linux platform, reducing development risk and recruitment difficulty.
• Flexible variant selection: Specifying the right combination of RAM, storage, and wireless avoids over-engineering the BOM for applications with modest requirements.
• Modular compliance certification: Wireless-equipped variants carry pre-certified RF compliance, reducing the regulatory testing burden when adding Wi-Fi or Bluetooth to a product.
• Long-term supply commitment: Raspberry Pi has committed to long-term availability of its Compute Modules, which matters considerably for embedded products with multi-year production runs.
• Separation of hardware and software development: Software can be developed and validated on an IO board while carrier board hardware is being designed in parallel, compressing the overall development timeline.
• Carrier board design freedom: Exposing all interfaces through a single high-density connector means the carrier can be optimised entirely around the product's requirements, with no compromises inherited from a general-purpose board layout.

Applications and use cases

Raspberry Pi CM business applications span a broad range of industries and product types. Some of the most common include:

• Industrial HMI and control panels: The CM5-based Edatec ED-HMI3120 series integrates the Compute Module into a ruggedised touchscreen display with industrial power input, watchdog, and crypto authentication - a ready-made embedded HMI solution for machine builders
• Edge gateways and connectivity computers: The Edatec ED-IPC1100 and ED-IPC3100 series use the CM0 and CM5 respectively, combining fieldbus interfaces, 4G connectivity, and DIN-rail mounting to create deployable industrial computers based on the Raspberry Pi platform.
• Medical and diagnostic devices: The combination of a controlled software environment, modular compliance certification, and established Linux drivers makes the CM platform attractive for Class I medical device integration.
• Digital signage and kiosk systems: Dual 4K display output and reliable long-term supply make the CM4 and CM5 well-suited to commercial display products requiring multi-year consistency.
• Retail and point-of-sale terminals: Low power draw, a compact footprint, and strong USB peripheral support suit embedded POS applications where the hardware must disappear inside a polished enclosure.
• Building automation and smart infrastructure: Wireless connectivity, Ethernet, and broad GPIO availability through a carrier board make the Compute Module a practical foundation for building management systems and access control devices.

Best suited for	Cost-sensitive, stable designs; extended temp applications	Higher compute demand; new designs with longer roadmap

For most new embedded product designs starting today, the CM5 is the stronger foundation — particularly where the product roadmap extends several years and compute requirements may grow. The CM4 remains highly relevant for cost-sensitive applications, designs already in production, and projects requiring the extended temperature range variants.

Getting Started: Development Kit and IO boards

For teams new to the Compute Module platform, or moving from CM4 to CM5, the Raspberry Pi CM5 Development Kit provides a complete starting point: a CM5 module and IO board with all the accessories needed to begin software development and hardware prototyping immediately. It is the most efficient way to validate the software stack before investing in carrier board design.

The CM4 IO Board and CM5 IO Board both expose the full interface set of their respective modules, providing a reference design that carrier board engineers can use to understand interface routing, power requirements, and recommended component selection before committing to a custom layout.

Best practices for Raspberry Pi CM business deployments

1. Define your interface requirements before selecting a variant. The carrier board design is driven by your I/O needs; the CM selection should follow from that, not the other way around.
2. Choose the Lite (0GB eMMC) variant if using external storage. Where the product will boot from an NVMe SSD or SD card via the carrier board, the Lite variant avoids paying for eMMC that will not be used.
3. Account for thermals early. Compute Modules in enclosed carrier board designs may need active or passive thermal management; the development kit phase is the right time to characterise this, not after tooling the enclosure.
4. Validate modular compliance early if shipping wireless products. The certified wireless module simplifies regulatory approval, but you still need to confirm the antenna design and placement on your carrier board do not invalidate the certification.
5. Plan for long-term software maintenance. Choose an OS distribution with a clear long-term support commitment; the Raspberry Pi OS LTS releases or Ubuntu LTS are both well-supported choices for production embedded deployments.
6. Register your project with your distributor. BCD Atlantik's project registration process for B2B CM customers ensures priority access to stock and supports volume pricing discussions before production ramp.

Frequently asked questions

What is the difference between the Raspberry Pi CM4 and a standard Raspberry Pi 4?

The CM4 uses the same processor and core silicon as the Raspberry Pi 4 Model B but removes the standard connectors and packages everything into a compact module designed to plug into a custom carrier board. It is not meant to be used standalone; it is a component for integration into a product.

Is the Raspberry Pi Compute Module suitable for commercial production runs?

Yes. As well as individually boxed modules, you can also purchase compute modules in bulk packs, where they come in trays. This reduces the time and cost of opening individual retail packages, and means they can easily be incorporated into a production workflow.

In addition, Raspberry Pi has committed to long-term supply of its Compute Modules specifically to support commercial and industrial customers with multi-year production needs. BCD Atlantik can support volume & bulk pack procurement and project registration for B2B customers.

Can I upgrade from CM4 to CM5 without redesigning my carrier board?

The CM5 uses a different connector than the CM4 and is not a drop-in replacement. A carrier board redesign is required. However, the software migration path is straightforward given the shared Raspberry Pi OS ecosystem.

What operating system do Raspberry Pi Compute Modules run?

Raspberry Pi OS (based on Debian) is the primary supported OS and is well-suited to embedded Linux deployments. Ubuntu and other Linux distributions are also supported on the CM platform.

Are extended temperature variants of the CM4 available?

Yes. Since March 2025, extended temperature CM4 variants rated from -40°C to +85°C have been available. These are not listed as standard shop variants; contact BCD Atlantik directly for pricing and availability.

What is the difference between the eMMC and Lite (0GB) variants?

The eMMC variants include onboard flash storage for the OS and application data. The Lite variant omits this, requiring the carrier board to provide an alternative boot storage, typically via an SD card slot or NVMe SSD on the carrier. Lite variants cost less and are preferred where external storage is already part of the design.

Do I need a development kit to get started?

Not strictly, but it is strongly recommended. The CM5 Development Kit provides the IO board, module, and accessories needed to begin software development and hardware bring-up without designing a carrier board first. It significantly reduces the time from evaluation to a validated software stack.

Can BCD Atlantik support ODM and custom hardware development around the Compute Module?

Yes. Alongside distribution, BCD Atlantik supports custom hardware development projects, including concept design, prototype development, and production support for products built on the Raspberry Pi Compute Module platform.

Key takeaways

• Raspberry Pi Compute Modules are designed for integration into custom carrier boards, not standalone use - this makes it well-suited to embedded product development.
• The CM4 remains a strong choice for cost-sensitive, extended-temperature, or already-in-production designs; the CM5 is the right foundation for new designs requiring more compute headroom.
• Modular wireless compliance certification, a mature Linux software stack, and long-term supply commitments are key commercial advantages of the Compute Module platform.
• Development kits and IO boards allow software development to proceed before carrier board hardware is finalised, compressing overall project timelines.
• Raspberry Pi CM business applications span HMI, edge computing, medical devices, digital signage, and industrial connectivity - with ready-made carrier solutions such as the Edatec IPC and HMI series also available

Conclusion

The Raspberry Pi Compute Module has earned its place in commercial embedded system design by combining genuine processing capability with an accessible software ecosystem, a flexible variant structure, and supply chain commitments that make it credible for multi-year production. Whether you are building an industrial HMI, an edge gateway, a connected kiosk, or a custom embedded controller, the CM platform offers a faster route from prototype to production than many proprietary alternatives.
