Sonar:bit for micro:bit Ultrasonic Sensor wonderworkshop Circuitry(PDF)Introduction Sonar: bit is an ultrasonic module with 3 5V working voltage. It is available to be used to 3. 3V or 5V micro controller system. With only one 3 wire(GVS) cable, it can work properly. Compared to the normal 4 wire ultrasonic module, it has saved one IO port. The measurement range of sonar: bit is 4cm 400cm. It can output stable and accurate measurement data with 1cm tolerance only. You can use this module to occasions like short distance
