It measures 155 × 86.5 mm and has 2 copper layers, 0.57 mm thick.
355 parts, built around the BC547 and BC557. 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 mengstr/24BitHexDecoder repository on GitHub, at the commit this page was made from: the board is kicad/24BitHexDecoder.kicad_pcb and its schematic kicad/24BitHexDecoder.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 mengstr before reusing the design.
