Questions
What parts does the Keyboard use?
191 parts, built around the ESP32-S3-WROOM-1-N16R2, LM1117DT-3.3 and VBUS54CV-HSF-G4-08. 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 Keyboard KiCad files?
From the thelostpotato27/keyboard repository on GitHub, at the commit this page was made from: the board is Keyboard.kicad_pcb and its schematic Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask thelostpotato27 before reusing the design.
