Waveshare CM5-DUAL-ETH-BASE

The Waveshare CM5-DUAL-ETH-BASE is a feature-rich carrier board designed for the Raspberry Pi Compute Module 5 (CM5). It provides dual Ethernet ports (1 Gbps + 2.5 Gbps), M.2 NVMe storage, dual HDMI 4K output, and a wide 7-36V input range, making it suitable for industrial IoT gateways, network appliances, edge computing, and digital signage.

Networking

The dual Ethernet configuration pairs a native 1000 Mbps Gigabit port with a USB-to-2.5G Ethernet controller for the second 2.5 Gbps port. This makes the board well-suited for network routing, firewall, or gateway applications where high-throughput dual-homed networking is required.

Storage & Expansion

An M.2 M KEY slot supports PCIe Gen2/Gen3 x1 NVMe SSDs in 2280, 2260, 2242, and 2230 form factors. NVMe boot is supported, enabling fast storage without SD cards. A TF card socket is available for CM5 Lite variants that lack onboard eMMC.

Display & Camera

Two HDMI ports provide dual 4K display output for kiosk or digital signage applications. Two 22-pin 0.5mm FFC MIPI interfaces support both CSI camera and DSI display connections (4-lane MIPI each).

I/O & Interfaces

USB connectivity includes one USB 3.2 Gen1 port (5 Gbps, 2A max), two USB 2.0 ports (480 Mbps shared, 2A total), and a USB Type-C port for flashing and power delivery. The standard 40-pin GPIO header provides access to I2C, I2S, SPI, UART, and general-purpose pins.

Security & Industrial Features

An onboard ATSHA204 encryption chip (I2C address 0x64) and CAT24C32 EEPROM (I2C address 0x50) provide hardware-based security and device identification for industrial deployments. The wide 7-36V DC input range accommodates diverse power environments. A 5V 4-pin JST-SH PWM fan header supports active cooling.

Physical Design

The base board measures 109.0 x 91.5mm. An optional metal enclosure (114.6 x 91.5 x 32.9mm) includes a CM5-FAN-4010-5V cooling fan with wall-mount and rail-mount support for industrial installation.
