Circuit diagrams and firmware source code for Gboard DIY keyboards

My first DIY keyboard / 3x6+3 split ortho
Switch42 is an open-source printed circuit board by zk-phi, from the zk-phi/switch42-keyboard repository on GitHub. It is a 2-layer board of 114.3 × 81 mm with 84 parts on 71 nets, routed with 1,173 tracks and 87 vias.
It is built around the SK6812MINI-E. Its parts include 25 switches, 24 diodes, 24 inductors, 2 connectors and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

It measures 114.3 × 81 mm and has 2 copper layers, 1.6 mm thick.
84 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/switch42-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.
