It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
82 parts, built around the 74HC00D, 74HC573, AT24C256N and DS1307+. 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 elekras/fs6809sbc repository on GitHub, at the commit this page was made from: the board is fs6809sbc.kicad_pcb and its schematic fs6809sbc.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 elekras before reusing the design.
