Questions
How big is the Keyboard PCB?
It measures 304.8 × 95.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
181 parts, built around the RP2040, W25Q128JVSIQ, 1N4148WT and ABM8-272-T3. 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 jbagnara/wheatboard repository on GitHub, at the commit this page was made from: the board is kicad/keyboard.kicad_pcb and its schematic kicad/flash.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 jbagnara before reusing the design.
