Dual Ethernet 1G / 2.5G Base Board for Raspberry Pi Compute Module 5 - Waveshare 32176

Description

The base board is designed for Raspberry Pi Compute Module 5, providing advanced networking and multimedia functionality for industrial and system applications. The board is equipped with two independent RJ45 Ethernet ports: one Gigabit Ethernet (1 Gb/s) and one 2.5 Gigabit Ethernet (2.5 Gb/s), enabling advanced networking solutions such as routers, communication gateways, and edge computing systems.

The board supports two HDMI outputs, allowing simultaneous 4K video display, as well as two four-lane MIPI interfaces (CSI/DSI) for connecting cameras and displays. The M.2 M Key connector (PCIe Gen2/Gen3 x1) enables the use of NVMe SSDs, significantly improving system performance compared to microSD storage.

A 40-pin GPIO header ensures compatibility with Raspberry Pi HAT and peripheral modules. The board also features USB 3.2 Gen1 and USB 2.0 ports, a PWM fan connector, BOOT and PWR buttons, an RTC circuit with backup battery support, and a wide power input range from 7 V to 36 V, making it suitable for industrial environments. The design supports both CM5 Lite and eMMC variants.
