Questions
How big is the Corne cherry PCB?
It measures 145.5 × 107.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Corne cherry use?
208 parts, built around the W25Q128JVSIQ, BQ24075RGT, XC6220B331MR and BSMD0603-050-12V. 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/keyboard repository on GitHub, at the commit this page was made from: the board is corne/crkbd-crkbd4/pcbs/corne-cherry/hotswap/corne-cherry.kicad_pcb and its schematic charybdis/Bastardkb Charybdis-PCB-thumbs main flex/flex.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 states no licence, so its author keeps all rights: ask yangxing844 before reusing the design.
