It measures 63 × 73.2 mm and has 6 copper layers, 1.6 mm thick.
89 parts, built around the ESP32-C3-WROOM-02-H4, BQ25792RQMR, CR6045-2R2N and SS54F. 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 dashonigkuchen/embedded-projects repository on GitHub, at the commit this page was made from: the board is car-seat-control/assets/schematics/chris/chris.kicad_pcb and its schematic car-seat-control/assets/schematics/chris/chris.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).
