Questions
How big is the Keypad PCB?
It measures 76.3 × 115.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keypad use?
100 parts, built around the ATMEGA32U4, SK6805E-J and B3FS-1002P. 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 Keypad KiCad files?
From the Fabian0520/FabiVan repository on GitHub, at the commit this page was made from: the board is keypad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keypad design in my own project?
Its repository states no licence, so its author keeps all rights: ask Fabian0520 before reusing the design.
