Raspberry Pi Compute Module 4 IO Board

Raspberry Pi Compute Module 4 IO Board

The Raspberry Pi 4 Compute Module 4 IO Board is a companion board designed for development purposes for the Raspberry Pi 4 Compute Module 4 (also available for purchase). It is designed to be used both as a development system for the Compute Module 4 and as an embedded board in final products.

This IO Board is designed to quickly enable the use of ready-to-use modules such as HATs and PCIe cards. User connectors have been placed on one side to facilitate easy connections.

It also provides a great opportunity to create prototypes with the Compute Module 4.
