It measures 138.6 × 120 mm and has 2 copper layers, 1.6 mm thick.
38 parts, built around the SN74AHCT1G125DBVR(UMW), K104K15X7RF5TL2, 10155435-00011LF and B3F-4050. 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 ZeusyBoy98/HexiLux repository on GitHub, at the commit this page was made from: the board is PCB/HexiLux-v1.kicad_pcb and its schematic PCB/HexiLux-v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
