It measures 236.5 × 172 mm and has 2 copper layers, 1.6 mm thick.
112 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 emibarg/VSource repository on GitHub, at the commit this page was made from: the board is VSource.kicad_pcb and its schematic VSource.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 emibarg before reusing the design.
