Questions
How big is the Numpad PCB?
It measures 76.2 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Numpad use?
50 parts, built around the XC6206P332MR and BAV70. 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 Numpad KiCad files?
From the arnstadm/numpad repository on GitHub, at the commit this page was made from: the board is numpad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 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).
