It measures 98.5 × 119 mm and has 2 copper layers, 1.6 mm thick.
11 parts, built around the DFR0654 and HC-SR04. 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 FelixStA52/BRACHIOSAURUS repository on GitHub, at the commit this page was made from: the board is KiCad/V1/main.kicad_pcb and its schematic KiCad/V1/main.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 FelixStA52 before reusing the design.
