## Description

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 4–400cm Range – Wide measurement distance for various applications ±1cm Accuracy – Stable, reliable distance readings micro:bit & Arduino Compatible – Easy integration with popular platforms Specifications Model – Sonar:bit (EF04089) Input Voltage – DC 3–5V Measurement Range – 4–400cm Accuracy – ±1cm Connection – 3-wire GVS Dimensions – 40.6mm × 51.06mm Weight – 12g Ideal For micro:bit distance sensing projects Smart cars and obstacle avoidance robots Arduino ultrasonic distance measurement STEM education and classroom activities Package Contents 1× Sonar:bit Ultrasonic Sensor 1× GVS Jumper Cable Resources Sonar:bit Guide Microsoft MakeCode Editor
