It is a compact 101x62mm solution for embedded projects.
What stands out
- Dual Ethernet ports offering 1Gbps and 2.5Gbps connectivity
- Compatible with all versions of Raspberry Pi Compute Module 5
- HDMI output supports 4K video resolution
- M.2 M-Key slot for PCIe Gen2/3 x1 storage
- Compact dimensions of 101x62x23.4mm
Who it fits
Good fit for
This board suits developers building network-intensive embedded systems. You will benefit from the 2.5Gbps port for high-throughput tasks like NAS access or fast file transfers. The dual ports allow you to isolate network traffic for security or stability. It is ideal for users who already own a Compute Module 5 and need a reliable expansion board. The included USB and MIPI interfaces support versatile peripheral connections for custom industrial or hobbyist setups.
Who should skip it
You should look elsewhere if you need an all-in-one computer. This is a carrier board, not a complete system. It requires a separate Compute Module 5 to function. If you want built-in storage without adding an M.2 drive, this may not fit your needs. Users seeking a plug-and-play desktop experience will find it lacking. It is also not suitable for those who need more than one HDMI output or extensive USB ports without additional hubs.
Verdict: This carrier board offers robust networking for Compute Module 5 users who need dual Ethernet speeds. It is a practical choice for specialized embedded projects requiring high-speed data transfer.
Key specs explained for this board
Ethernet: 1Gbps + 2.5Gbps
You get two distinct network speeds on one board. The Gigabit port handles standard traffic, while the 2.5Gbps port offers faster data transfer. This lets you separate management tasks from heavy file transfers. If you need high-speed local storage access or frequent large file moves, the 2.5Gbps port is essential. Standard Mini PCs often offer only one port, making this dual setup more flexible for complex network setups.
Video Resolution: 4K
The board supports 4K output via its HDMI port. This means you can connect a high-resolution display for clear text and sharp images. It is suitable for media centers or professional displays that require high detail. If you plan to use the Compute Module 5 as a desktop replacement or digital signage player, 4K support ensures the visual experience remains crisp and modern compared to older 1080p-only solutions.
Interface: CM5-Compatible
This carrier board is designed specifically for all versions of the Raspberry Pi Compute Module 5. You must have the CM5 to use this hardware. It does not work with older modules or standard Raspberry Pi boards. This strict compatibility ensures you get the full feature set intended by the manufacturer. When shopping, verify your module version to avoid purchasing incompatible hardware that cannot connect properly.
Storage: M.2 M-Key
The board includes an M.2 M-Key slot supporting PCIe Gen2 or Gen3 x1. This allows you to add a fast NVMe SSD for storage. It is ideal for improving boot times and application loading speeds. If you need more than the module's internal storage, this slot provides a reliable upgrade path. Compare this with Mini PCs that lack expansion slots, as this offers greater flexibility for future storage additions.
Design and build overview
According to the listing, this board measures 101 by 62 by 23.4 millimeters. That compact footprint allows you to mount it in tight spaces or integrate it into custom enclosures. The low profile means it fits under desks or inside small chassis without taking up much vertical room. You do not need extra clearance for tall components.
The layout prioritizes connectivity over bulk. You get a 40-pin GPIO header for general purpose input and output tasks. Two USB ports are available, one USB 3.2 Gen1 and one USB 2.0. A Type-C port supports USB 2.0 data. Dual MIPI connectors handle display outputs, while an HDMI port supports 4K video. This mix lets you connect peripherals without needing a hub.
Storage options include an onboard microSD slot for modules without eMMC. An M.2 M-Key slot supports PCIe Gen2 or Gen3 x1 drives for faster storage. A 5V 4-pin PWM fan connector is present for active cooling. The board runs on DC 5V at 5 amps. This power requirement means you need a reliable adapter nearby. The design keeps things simple and functional for embedded projects.
Setup and daily use
This carrier board requires a Raspberry Pi Compute Module 5 to function. It is not a standalone computer. You must purchase the CM5 separately. The board connects directly to the module’s interface. This design keeps the footprint small. You will need to provide power via a DC 5V/5A source. The listing does not include a power adapter. You also need to source the Compute Module itself. If your module lacks eMMC storage, you must insert a microSD card into the onboard slot. This card holds the operating system. For faster storage, you can install an M.2 SSD in the M-Key slot. The board supports PCIe Gen2 or Gen3 x1 speeds. This allows for quick data access. Cooling is managed by a 5V 4-pin PWM fan connector. You must attach a compatible fan to prevent overheating during sustained workloads. Daily use involves plugging in your network cables. The dual RJ45 ports allow you to connect to different networks. You can use the Gigabit port for general internet access and the 2.5Gbps port for local file transfers or server tasks. Video output goes through the HDMI port. It supports 4K resolution. This makes it suitable for desktop-like tasks. You can also connect peripherals via the USB ports. The 40-pin GPIO header lets you attach sensors or other hardware. This setup is ideal for users who already own a CM5 and need flexible networking. It is not for beginners looking for a plug-and-play system.
What You Need Before Buying
You need a Raspberry Pi Compute Module 5 to use this board. It is a carrier board, not a complete computer. You must buy the CM5 separately. Check your specific CM5 version for compatibility. This board supports all versions, but you should verify your existing hardware. You also need a 5V/5A power supply. The listing specifies this exact power requirement. Do not use a weaker adapter. You will likely need a case for protection. The board exposes many connectors. A simple enclosure helps prevent damage. This product fits into the small form factor category. It is ideal for users who already own a CM5. If you need a ready-to-use mini PC, look elsewhere. This option suits builders who want dual Ethernet speeds. It allows you to separate network traffic easily. You get 4K video output and multiple USB ports. Storage options include microSD and M.2 slots. This setup is for specific networking tasks. It is not for general desktop use. You must plan your power and cooling carefully.
Check before you buy
- Confirm you have a Raspberry Pi Compute Module 5.
- Verify your CM5 version is supported by this carrier board.
- Ensure you have a 5V 5A DC power supply.
- Check if you need a protective case for the board.
