It measures 130 × 90 mm and has 2 copper layers, 1.6 mm thick.
30 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 Nalin-Angrish/Robocon25 repository on GitHub, at the commit this page was made from: the board is pcb/Robocon.kicad_pcb and its schematic pcb/Robocon.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 Nalin-Angrish before reusing the design.
