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.\n\nWith 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.\n\nKey Features\n\n\n3–5V Compatible – Works with both 3.3V and 5V microcontrollers\n\n3-Wire GVS Connection – Uses only one I/O port instead of two\n\n4–400cm Range – Wide measurement distance for various applications\n\n±1cm Accuracy – Stable, reliable distance readings\n\nmicro:bit & Arduino Compatible – Easy integration with popular platforms\n\n\nSpecifications\n\n\nModel – Sonar:bit (EF04089)\n\nInput Voltage – DC 3–5V\n\nMeasurement Range – 4–400cm\n\nAccuracy – ±1cm\n\nConnection – 3-wire GVS\n\nDimensions – 40.6mm × 51.06mm\n\nWeight – 12g\n\n\nIdeal For\n\nmicro:bit distance sensing projects\nSmart cars and obstacle avoidance robots\nArduino ultrasonic distance measurement\nSTEM education and classroom activities\n\n\nPackage Contents\n\n1× Sonar:bit Ultrasonic Sensor\n1× GVS Jumper Cable\n\n\nResources\n\nSonar:bit Guide\nMicrosoft MakeCode Editor\n","vendor":"ElecFreaks","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4687,"title":"Default Title","sku":"EF-EF04089","price":11.21,"on_sale":false,"in_stock":true,"available_quantity":104,"option1":"Default Title"}]}
