Sonar:bit for micro:bit Ultrasonic Sensor Distance Measuring 3V/5V

Sonar:bit is a 3-wire ultrasonic distance sensor designed for micro:bit and Arduino projects. Operating on 3–5V, it works directly with both 3.3V and 5V systems using a single GVS cable — saving an I/O port compared to traditional 4-wire ultrasonic modules.

With a measurement range of 4–400cm and ±1cm accuracy, Sonar:bit delivers stable, reliable distance readings for obstacle avoidance, distance measurement, and interactive projects. Program it easily with Microsoft MakeCode for micro:bit.
