Questions
How big is the Mini keyboard PCB?
It measures 158.8 × 120.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mini keyboard use?
87 parts, built around the MX1A-11NN, ABX00027 and 1N4148W. 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 Mini keyboard KiCad files?
From the hdlguy/kicad repository on GitHub, at the commit this page was made from: the board is mini_keyboard/kicad/mini_keyboard.kicad_pcb and its schematic alinx_carrier/alinx_carrier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini keyboard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
