It measures 233.4 × 181 mm and has 2 copper layers, 1.6 mm thick.
43 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 undertaker318/S-Keyboard repository on GitHub, at the commit this page was made from: the board is Split Keyboard.kicad_pcb and its schematic Split Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
