Questions
How big is the Numpad project PCB?
It measures 76.5 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Numpad project use?
78 parts, built around the ATMEGA32U4 and WS2812E-1313. 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 project KiCad files?
From the falsonix/fx19 repository on GitHub, at the commit this page was made from: the board is pcb/numpad_project.kicad_pcb and its schematic pcb/numpad_project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Numpad project design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
