The Compute Module 4 IO Board is a Raspberry Pi Compute Module 4 companion board. It is intended for use as a Compute Module 4 development system as well as an embedded board integrated into end products. The IO board is intended to allow you to easily build systems using off-the-shelf components such as HATs and PCIe cards, which may include NVMe, SATA, networking, or USB. To simplify enclosures, the major user connectors are positioned along one side to make enclosures simple.
