It measures 66 × 50 mm and has 2 copper layers, 1.6 mm thick.
19 parts, built around the 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 copaland/smartCar repository on GitHub, at the commit this page was made from: the board is EDU_CAR_circuit/wroom-car/wroom-car.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask copaland before reusing the design.
