439 parts, built around the RP2354B, 74AHCT125D, CH224K and FSUSB42MUX. 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 DEV-ajthedj/Keyboard repository on GitHub, at the commit this page was made from: the board is keyboard.kicad_pcb and its schematic display.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 DEV-ajthedj before reusing the design.
