Raspberry Pi Compute

Module 4 IO Board.

The Raspberry Pi Compute Module 4 IO Board (CM4IO) is designed to assist in the development of products that make

use of the Raspberry Pi Compute Module 4. The Raspberry Pi Compute Module 4 IO Board contains many of the

interfaces that the Raspberry Pi 4, Model B has, and for general usage you should refer to Raspberry Pi 4, Model B

documentation. The significant difference between CM4IO and Raspberry Pi 4, Model B is the addition of a single PCIe

socket. The CM4IO has been designed as both a reference design for CM4 or to be used directly as a product with the

possible addition of PCIe Cards and Raspberry Pi HATs.
