It measures 292.6 × 146.9 mm and has 2 copper layers, 0.09 mm thick.
143 parts, built around the USBLC6-2SC6 and 1N4148W. 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 elagil/lechuza repository on GitHub, at the commit this page was made from: the board is pcb/main.kicad_pcb and its schematic pcb/keys.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
