Questions

What parts does the Cao use?

22 parts, built around the ATMEGA328P-AU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Cao KiCad files?

From the celeloup/42_electronics repository on GitHub, at the commit this page was made from: the board is cao_00/cao/cao.kicad_pcb and its schematic cao_00/cao/button.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Cao design in my own project?

Its repository states no licence, so its author keeps all rights: ask celeloup before reusing the design.
