Dual Gigabit 5G 4G Ethernet Base Board for Raspberry Pi Compute Module CM4

Download CM4 ETH Base Board User Guide

This Ethernet Board is compatible with the Raspberry Pi Compute Module CM4 series. Due to its support for 5G and 4G cellular modules, this baseboard is highly suitable for integration into end products. The gigabit baseboard features an M.2 B KEY interface to connect with the 4G / 5G module and dual Gigabit Ethernet RJ45. The board also features a Nano SIM card slot. In addition, the baseboard features a 40-PIN Raspberry Pi GPIO Header and 2x USB 3.2 GEN1 ports.

Connects with Cellular Modules Compatible with M.2 B KEY

An additional communication module is required to enable 5G / 4G cellular network function.
