It measures 54 × 48 mm and has 2 copper layers, 1.6 mm thick.
18 parts, built around the ESP32-WROOM-32 and LM2596S-3.3. 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 kallel-amina/IOT-access-control repository on GitHub, at the commit this page was made from: the board is hardware/pcb/access_controller/access_controller.kicad_pcb and its schematic hardware/pcb/access_controller/access_controller.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 kallel-amina before reusing the design.
