Compute Module 4 IO Board

Exposing every interface from Raspberry Pi Compute Module 4, the Compute Module 4 IO Board provides a development platform and reference base-board design for our most powerful Compute Module yet.

Introducing the Raspberry Pi Compute Module 4 and IO Board

Overview

The Compute Module 4 IO Board is a companion board for Raspberry Pi Compute Module 4 (supplied separately). It is designed for use both as a development system for Compute Module 4 and as an embedded board integrated into end products.
The IO board is designed to allow you to create systems quickly using off-the-shelf parts such as HATs and PCIe cards, which might include NVMe, SATA, networking, or USB. The major user connectors are located along one side to make enclosures simple.

The Compute Module 4 IO Board also provides an excellent way to prototype systems using Compute Module 4.
