The Compute Module 4 contains the internal components of a Raspberry Pi 4 but lacks development-friendly ports, this IO Board provides access to these ports for easy development.

The Compute Module 4 IO Board is a companion board for Raspberry Pi Compute Module 4, designed for development and as an embedded board in end products.

The board allows quick system creation using off-the-shelf parts like HATs and PCIe cards for NVMe, SATA, networking, or USB.

Major user connectors are located on one side to simplify enclosures and provide an excellent way to prototype systems.

The Compute Module 4 IO Board offers access to all the interfaces of the Raspberry Pi Compute Module 4 and serves as an ideal development platform and reference base-board design for industrial applications.

Please note that the Compute Module 4 IO Board does not include the matching Compute Module 4, which must be purchased separately.
