Questions

How big is the Chococorne PCB?

It measures 261.7 × 87.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Chococorne use?

112 parts. 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 Chococorne KiCad files?

From the idank/keyboards repository on GitHub, at the commit this page was made from: the board is chocorne hotswap/chococorne.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Chococorne design in my own project?

Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
