It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
33 parts, built around the M2.5. 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 aosho44/Mars-Rover repository on GitHub, at the commit this page was made from: the board is Mars Rover/Mars Rover Ki-Cad/Mars Rover.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask aosho44 before reusing the design.
