It measures 44 × 49 mm and has 2 copper layers, 1.6 mm thick.
2 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 tufourn/cirque_breakout repository on GitHub, at the commit this page was made from: the board is track.kicad_pcb and its schematic track.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 tufourn before reusing the design.
