Questions
How big is the Corne cherry PCB?
It measures 133.8 × 91.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Corne cherry use?
96 parts, built around the SK6812MINI-E. 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 maxhbr/things repository on GitHub, at the commit this page was made from: the board is keyboards/corne-cherry/corne-cherry/corne-cherry.kicad_pcb and its schematic keyboards/reviung41/reviung41/pcb/ver1.4/reviung41.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 maxhbr before reusing the design.
