It measures 100 × 68.5 mm and has 2 copper layers, 1.6 mm thick.
43 parts, built around the AMS1117-3.3 and USB6B1. 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 maxryan4/Keyboard repository on GitHub, at the commit this page was made from: the board is PCB/Keyboard.kicad_pcb and its schematic PCB/Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask maxryan4 before reusing the design.
