    I/O card for Compute Module 4 (CM4)

    Exposing every interface of the Compute Module 4, the CM4 IO board provides a development platform and reference board for project design around CM4.


    The Compute Module 4 IO board is an add-on board for the Raspberry Pi Compute Module 4, allowing a CM4 project to be started quickly. It is an excellent way to prototype systems using the Compute Module 4.

    It is designed to be used both as a development system for Compute Module 4 and as an embedded board that can be directly integrated into finished products.

    The IO board has been designed with the objective of quickly creating systems using off-the-shelf building blocks such as HATs and PCIe cards.
    The main interface connectors are located along one side to simplify encapsulation in a package.
