## Description

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.
