Questions
How big is the Kmykbd PCB?
It measures 297.6 × 78.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kmykbd use?
120 parts, built around the WS2812B. 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 Kmykbd KiCad files?
From the robin15/pcb repository on GitHub, at the commit this page was made from: the board is kmykbd/kb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kmykbd design in my own project?
Its repository states no licence, so its author keeps all rights: ask robin15 before reusing the design.
