Questions
How big is the Numpad PCB?
It measures 81.3 × 100.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Numpad use?
53 parts, built around the ATMEGA32U2-AU, USBLC6-2SC6 and DX07S016JA1R1500. 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 aaron-lucas/NumpadPCB 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 states no licence, so its author keeps all rights: ask aaron-lucas before reusing the design.
