It measures 101.6 × 101.6 mm and has 4 copper layers, 1.6 mm thick.
60 parts, built around the ATF22V10C-7PX, 74HCT125PW, 74LS670 and AS6C4008-55PCN. 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 hoglet67/SBC09 repository on GitHub, at the commit this page was made from: the board is kicad/sbc09.kicad_pcb and its schematic kicad/sbc09.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 hoglet67 before reusing the design.
