We have quite a few project ideas and uses for the Raspberry Pi, and we have looked at some other options from the Raspberry Pi foundation (like the Raspberry Pi Pico 2 / Pico 2 W), and today is no different. After almost 4 years, the Raspberry Pi Foundation released the Raspberry Pi Compute Module 5. What is the Compute Module and how does it differ from the normal Raspberry Pi? Let’s dive right in!
What Is the Raspberry Pi Compute Module 5?
The Compute Module 5 is a slimmed-down version of the Raspberry Pi 5 designed for embedded systems and industrial applications. While it shares much of the same technology as the Pi 5, it’s packaged in a compact form factor that lacks the ports and connectors you’d find on a typical Raspberry Pi. Instead, it’s designed to be used as part of a larger custom circuit board or connected to an IO board that provides access to the necessary inputs and outputs.
How Does It Work?
At its core, the CM5 is powered by the same quad-core ARM Cortex-A76 processor and VideoCore VII GPU as the Raspberry Pi 5, making it a powerful computing module. It connects to the outside world using high-density connectors instead of the usual USB, HDMI, and GPIO ports.
This modular design is perfect for custom hardware solutions. For instance, manufacturers can design their own carrier boards with specific ports and features that meet their needs while using the CM5 for processing power.
What Is the Raspberry Pi Compute Module 5 IO Board?
If you want to use the CM5 without designing your own hardware, the Raspberry Pi Compute Module 5 IO Board is your best friend. This board acts as an intermediary, providing:
- HDMI ports for video output.
- USB ports for peripherals like a keyboard, mouse, or storage.
- Ethernet for internet connectivity.
- GPIO pins for interfacing with other devices and sensors.
- M.2 slot for fast storage or expansion.
In short, the IO Board gives you all the connections and features you’d expect from a regular Raspberry Pi, making it much easier to start experimenting with the CM5.
Example Projects for the Raspberry Pi Compute Module 5
The CM5 is ideal for projects that require a compact design or need to integrate directly into other hardware. Here are a few ideas:
- Smart Home Hubs
Create a custom home automation hub that can control lights, cameras, and sensors while fitting into a sleek enclosure. - Industrial Automation
Use the CM5 to power machinery, monitor sensors, or control robotic arms in industrial settings. - Custom Media Players
Build a slim, high-performance media player that connects to TVs or displays via the IO Board. - IoT Devices
Design smart devices like connected thermostats, weather stations, or security systems. - Prototypes for Custom Hardware
If you’re developing a product, the CM5 allows you to test your design before scaling production.
Raspberry Pi Compute Module 5 vs. Raspberry Pi 5
| Feature | Compute Module 5 (CM5) | Raspberry Pi 5 |
|---|---|---|
| Form Factor | Slim module, no ports | Standard board with built-in ports |
| Connectivity | Via carrier board or custom PCB | USB, HDMI, Ethernet, and GPIO built-in |
| Usage | Embedded systems and industrial | General-purpose computing |
| Flexibility | Highly customizable | Plug-and-play |
The CM5 is all about customization, whereas the Pi 5 is ready to go out of the box.
Options for the Raspberry Pi Compute Module 5
The CM5 comes in several variants to suit different needs:
- Memory Options: Choose from 2GB, 4GB, or 8GB of LPDDR4x RAM depending on the complexity of your projects.
- eMMC Storage: Available with 16GB (available only in 2025), 32GB, or 64GB of built-in storage. Using it with the IO Board will give you a NVMe slot, so take that into account for more storage space (Read more on the Raspberry Pi M.2 NVMe cards)
- Wi-Fi and Bluetooth: Some versions include built-in Wi-Fi 5 and Bluetooth 5.0 for wireless connectivity.
Conclusion
The Raspberry Pi Compute Module 5 is a powerful and flexible option for those looking to create custom hardware solutions. While it lacks the out-of-the-box usability of the Raspberry Pi 5, its compact design and modular approach make it ideal for industrial applications, prototypes, and space-saving projects. Pairing it with the Compute Module 5 IO Board makes it accessible for hobbyists and developers without the need for custom carrier boards.
Whether you’re automating your home, building an IoT device, or developing the next big tech product, the CM5 offers the power and flexibility to bring your ideas to life. With options for memory, storage, and wireless connectivity, there’s a CM5 for every project.
