About the CM0IO PCB
CM0IO is an open source PCB design by axoulc, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 65 × 67.5 mm, with 9 components from 7 distinct parts.
By type, the board carries 8 connectors and 1 module.
From the project
HWBoard Bike Computer PCB: A KiCad hardware project for building a custom printed circuit board (PCB) designed for a feature-rich, open-source bike computer. Powered by Raspberry Pi Compute Module 0 (CM0).
These files have been created in version 9 of KiCAD.
Some of the 3d models need to be downloaded form the following places and put into the CM4IO.3dshapes directory some models are approximations.

The models provided in the 3dmodels directory are from various manufacturers including RaspberryPi, Hirose. Terms and conditions for the use of the models remain with the original manufacture.
