Questions
What parts does the Keyboard use?
53 parts, built around the RP2040, W25Q128JVSIQ, SN74AHCT1G125DBVR(UMW) and SRV05-4-P-T7. 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 joshajohnson/keyboard-template repository on GitHub, at the commit this page was made from: the board is hardware/template/keyboard.kicad_pcb and its schematic hardware/template/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 joshajohnson before reusing the design.
