Mini-Computer Kit for CM5 (Dual Gigabit, Board and Case)

Evaluate and integrate the Raspberry Pi Compute Module 5 (CM5) with ease using this compact Dual Gigabit Ethernet base board. Ideal for industrial routers, edge computing and custom embedded systems, it delivers two full-speed 10/100/1000 Mbps LAN ports alongside USB 3.2 Gen 1 and GPIO connectivity in a neat 55 × 68 mm footprint.

Key Features

• Dual RJ45 Gigabit Ethernet ports (10/100/1000 Mbps)
• USB 3.2 Gen 1 Type-A port for high-speed peripherals
• 40-pin Raspberry Pi GPIO header plus CM5 socket (all variants supported)
• TF card slot for CM5 Lite (no‐eMMC) boot and storage
• 4-wire fan header (5 V) with speed control and tachometer
• USB-C 5 V power input (also for eMMC programming)
• PSW and BOOT buttons for power and programming mode
• Anti-slip rubber feet, clear labelling and magnetic top cover (optional)

Detailed Description

This mini base board is designed both for rapid prototyping and seamless integration into end products. The RTL8111H Gigabit NIC chip manages the two LAN ports, with ETHERNET 0 mapped to the CM5’s native port and ETHERNET 1 driven via PCIe. A USB 3.2 Gen 1 port ensures you can attach cameras, storage or other high-speed devices. GPIO and TF card access let you expand and boot Lite modules without soldering.

An optional aluminium alloy case provides robust protection, magnetic removal for easy access and a heatsink-enhanced top for efficient thermal dissipation. Anti-slip pads, clear silkscreen labels and a recessed fan header ensure professional polish in industrial environments.
