It measures 45.5 × 38.4 mm and has 2 copper layers, 1.6 mm thick.
50 parts, built around the CH340E, LM321, TS2431BILT and SS8050. 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 Churrosoft/scanner_ISO9141 repository on GitHub, at the commit this page was made from: the board is scanner_v1/scanner_v1.kicad_pcb and its schematic scanner_v1/scanner_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
