The Raspberry Pi Foundation has just announced the release of the CAD files for the Compute Module IO Board. Here’s what they say about the format that they’ve been released in:
The design files are the Cadence OrCAD schematic file, Cadence Allegro PCB file and the full board Gerbers, bill of materials (BOM) and PDF version of the schematic. People should be able to take the design and easily modify it, or just take the Gerber files and create copies of the board if that’s what they want to do.
