It measures 351.5 × 216.5 mm and has 2 copper layers, 1.6 mm thick.
13 parts, built around the ESP32-WROOM-32, DHT11 and AMS1117-3.3. 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 Mahesprabhu45/BLE_SENSOR_PCB repository on GitHub, at the commit this page was made from: the board is BeePrecise_BLE sensor/Beeprecise-BLE sensor pcb/BeePrecise_BLE_Sensor.kicad_pcb and its schematic BeePrecise_BLE sensor/Beeprecise-BLE sensor pcb/BeePrecise_BLE_Sensor.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 Mahesprabhu45 before reusing the design.
