A compact transparent keyboard
Switch42 is an open-source printed circuit board by zk-phi, from the zk-phi/equilibrium-keyboard repository on GitHub. It is a 2-layer board of 241.4 × 76.2 mm with 151 parts on 130 nets, routed with 1,492 tracks and 85 vias.
It is built around the SK6812MINI-E. Its parts include 67 inductors, 42 switches, 41 diodes and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

It measures 241.4 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
151 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.
From the zk-phi/equilibrium-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.
Its repository states no licence, so its author keeps all rights: ask zk-phi before reusing the design.
