ADAFRUIT VL53L4CX TIME OF FLIGHT DISTANCE SENSOR - ~1 TO 6000MM - STEMMA QT / QWIIC, ADAFRUIT 5425

Adafruit VL53L4CX Time of Flight Distance Sensor

The VL53L4CX is a high-performance Time-of-Flight (ToF) distance sensor breakout board from STMicroelectronics, re-packaged by Adafruit with a user-friendly STEMMA QT / Qwiic connector for easy, solderless connection. It is designed for precision distance measurement from approximately 1 mm up to 6000 mm (6 m), making it suitable for robotics, obstacle detection, interactive systems, and more.

Key Features

• Long-range distance sensing: approximately 1 mm to 6000 mm measurement range.

• ToF technology: uses an invisible 940 nm laser VCSEL emitter and advanced histogram-based firmware to measure time-of-flight for precise readings.

• Narrow field-of-view (~18°) for targeted detection and minimal interference.

• Multi-object detection capability: can identify when more than one object is in view and report multiple distances.

• Works with 2.8–5 V logic and power thanks to a built-in regulator and level shifter, compatible with many microcontrollers.

• I²C interface with STEMMA QT / Qwiic connector for plug-and-play use with supported boards.

• Small breakout size with standard headers included, easy to integrate into prototypes and embedded designs.

Typical Applications

• Autonomous robots and drones needing accurate distance or proximity sensing.

• Interactive installations or smart objects detecting user presence or gestures.

• Embedded systems measuring clearance, height, or gap using a compact sensor.

• DIY electronics or educational kits where simple, high-performance distance measurement is required.
