Questions
How big is the 3x4-12-key numpad PCB?
It measures 57.2 × 94.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 3x4-12-key numpad use?
37 parts, built around the ATMEGA32U2-AU. 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 3x4-12-key numpad KiCad files?
From the eliassjogreen/Shuttle repository on GitHub, at the commit this page was made from: the board is Electronics/3x4-12-key-numpad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 3x4-12-key numpad 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).
