It measures 229.5 × 76.5 mm and has 2 copper layers, 1.6 mm thick.
74 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 tangzero/simple36 repository on GitHub, at the commit this page was made from: the board is pcb/simple36.kicad_pcb and its schematic pcb/simple36.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 tangzero before reusing the design.
