The VL53L1X is a laser-ranging sensor from STMicroelectronics, capable of measuring distances up to 4 meters. It employs a 940-nanometer invisible laser beam (class 1 safety) and a SPAD photodetector (single-photon avalanche diode) to measure the time traveled by the laser beam between the sensor and the target. This technique is called Time-of-flight (ToF) and allows the calculation of the path traveled by the laser beam.

Here are the board’s main features:

  • Distance Measurements up to 4 meters. Distance measurements are independent of ambient light conditions and target characteristics, like color, shape, or texture. These factors will influence the maximum distance capable of being measured. The minimum distance for accurate measurements is 4cm.
  • 3.3V and 5V Power Supply. The onboard voltage regulator accepts anything from 2.6V to 5.5V to supply the VL53L1X sensor with a constant voltage of 2.8V.
  • I²C Communication. The sensor communicates through the I²C protocol using the address 0x29.
