It measures 29.2 × 50.5 mm and has 2 copper layers, 1.6 mm thick.
16 parts, built around the ATTINY412-SSN. 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 GerardZ/AtTiny_Die repository on GitHub, at the commit this page was made from: the board is Documents/Kicad/AtTiny412_DobbelSteen.kicad_pcb and its schematic Documents/Kicad/AtTiny412_DobbelSteen.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 GerardZ before reusing the design.
