It measures 72.4 × 78.7 mm and has 2 copper layers, 1.66 mm thick.
91 parts, built around the ATTINY9-TS8R, TPA3111D1QPWPRQ1, HUSB238_002DD and L78L05ABUTR. 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 Diabltica/AudioInterface repository on GitHub, at the commit this page was made from: the board is AudioInterface.kicad_pcb and its schematic AudioInterface.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 Diabltica before reusing the design.
