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.

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

Requires 12 V power supply sold separately.
