It measures 132 × 98.5 mm and has 2 copper layers, 1.6 mm thick.
106 parts. 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 foostan/wfkbd repository on GitHub, at the commit this page was made from: the board is pcb/wfkbd.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 foostan before reusing the design.
