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.

Key Features

  • 3–5V Compatible – Works with both 3.3V and 5V microcontrollers
  • 3-Wire GVS Connection – Uses only one I/O port instead of two
