Questions
How big is the Keyboard PCB?
It measures 293.1 × 126.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
170 parts, built around the RP2040, W25Q128JVSIQ, 1N4148WS and YSX321SL. 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 sagarreddypatil/keyboard repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic pcb/pcb.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 sagarreddypatil before reusing the design.
