Questions
How big is the Corne cherry PCB?
It measures 278 × 93.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Corne cherry use?
244 parts, built around the BQ24075RGT, XC6220B331MR, PMEG4010CEJ and AO3401A. 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 Corne cherry KiCad files?
From the yangxing844/corne-wireless repository on GitHub, at the commit this page was made from: the board is corne-cherry.kicad_pcb and its schematic corne-cherry.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Corne cherry design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
