Questions
How big is the Switch42 PCB?
It measures 136.5 × 73.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Switch42 use?
85 parts, built around the SK6812MINI-E. 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 Switch42 KiCad files?
From the zk-phi/pollux-keyboard repository on GitHub, at the commit this page was made from: the board is pcb/switch42.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switch42 design in my own project?
Its repository states no licence, so its author keeps all rights: ask zk-phi before reusing the design.
