It measures 41.9 × 35 mm and has 2 copper layers, 1.6 mm thick.
14 parts, built around the L293D. 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 rohitCodeRed/toy_car_motor_driver_pcb repository on GitHub, at the commit this page was made from: the board is toy_car_motor_driver.kicad_pcb and its schematic toy_car_motor_driver.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 rohitCodeRed before reusing the design.
