It measures 40.8 × 52 mm and has 2 copper layers, 1.6 mm thick.
48 parts, built around the CD4051BE. 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 LiamHowell/Remote_Hacker_PCB repository on GitHub, at the commit this page was made from: the board is Remote_Hacker/Remote_Hacker.kicad_pcb and its schematic Remote_Hacker/Remote_Hacker.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 LiamHowell before reusing the design.
