It measures 56.5 × 21 mm and has 2 copper layers, 1.6 mm thick.
11 parts. 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 Sande881/RnC_Taskphase repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/PCB.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).
