Raspberry Pi Compute Module CM4 IO Board
- Raspberry Pi Foundation
Like the IO boards for earlier Compute Module products, this breaks out all the interfaces from the Compute Module to standard connectors, providing a ready-made development platform and a starting point for your own designs. CAD for the IO board is available in KiCad format.
In addition to serving as a development platform and reference design, the IO board is a finished product in its own right: if you require a Raspberry Pi that supports a wider range of input voltages, has all its major connectors in a single plane, or allows you to attach your own PCI Express devices, then Compute Module 4 with the IO Board does what you need.
