It measures 299.5 × 130 mm and has 2 copper layers, 1.6 mm thick.
158 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 marby3/sumnight57 repository on GitHub, at the commit this page was made from: the board is sumnight_v2/Kicad_data/SumNight57/SumNight57.kicad_pcb and its schematic sumnight_v1/Kicad_data/SumNight57/SumNight57.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).
