Questions
How big is the Numpad PCB?
It measures 104 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Numpad use?
54 parts, built around the SK9822. 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 Denrage/customkeyboard repository on GitHub, at the commit this page was made from: the board is numpad/numpad/numpad.kicad_pcb and its schematic TKL/TKL/FifthRowKeys.kicad_sch. 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 Denrage before reusing the design.
