This SparkFun Distance Sensor Breakout uses the VL53L1X next-generation Time-of-Flight (ToF) sensor module to deliver highly accurate measurements at long ranges for its size. Unlike standard IR sensors that rely on reflected light intensity, the VL53L1X uses a VCSEL (Vertical Cavity Surface Emitting Laser) to emit an infrared laser and measure the time it takes for the light to bounce back to the target. This allows you to measure distances from 40mm to 4 meters with millimetre resolution, regardless of the object's colour or surface texture.
To make getting your readings as easy as possible, all communication is enacted exclusively via I2C. We've routed this through our handy Qwiic Connect System, so no soldering is required to connect it to the rest of your system. However, we have still broken out 0.1”-spaced pins in case you prefer to use a standard breadboard.
This sensor is packed with features that make it adaptable to different environments:
Before you start integrating this breakout into your project, keep a few key details in mind. First, the sensor ships with a protective liner on the optical glass that must be removed before use; otherwise, it will throw off your readings. Second, power the board with 2.6V-3.5V for proper operation. Finally, the I2C address is hardware-defined at 0x29. So, if you plan to use multiple sensors on a single bus, you will need a multiplexer, such as the SparkFun Qwiic Mux Breakout.
