BlueDot VL53L1X Board

The VL53L1X is a laser-ranging sensor from STMicroelectronics, capable of measuring distances up to 4 meters. It employs a 940 nanometers 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.

Features:

• Distance Measurements up to 4 m. Distance measurements are independent of ambient light conditions and target characteristics, like color, shape or texture. These factors will however influence the maximum distance capable of being measured. The minimum distance for accurate measurements is 4 cm.
• 3.3V and 5V Power Supply. The on-board 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. 
• Data Transfer with both 5V and 3.3V devices. While devices like the Arduino Uno interpret a 5V signal as a logic HIGH, the BMP388 uses 3.3V as a logic HIGH. The on-board logic level converter translates the 5V signals into 3.3V signals and vice-versa.
