It measures 428 × 147 mm and has 2 copper layers, 1.6 mm thick.
190 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 AndrewBDavis/Copam repository on GitHub, at the commit this page was made from: the board is copam.kicad_pcb and its schematic copam.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 AndrewBDavis before reusing the design.
