xcluma VL53L0X Time-of-Flight (ToF) Laser Ranging Sensor Breakout 940nm GY-VL53L0XV2 Laser Distance Module I2C IIC

• The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. This board is a carrier for the VL53L0X, so we recommend careful reading of the VL53L0X datasheet (1MB pdf) before using this product.
• Ranging measurements are available through the sensor’s I²C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output. The VL53L0X is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for microcontrollers operating at 3.3 V or 5 V.
• The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor’s accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.)
• PIN VDD Regulated 2.8 V output. Almost 150 mA is available to power external components. (If you want to bypass the internal regulator, you can instead use this pin as a 2.8 V input with VIN disconnected.) VIN This is the main 2.6 V to 5.5 V power supply connection. The SCL and SDA level shifters pull the I²C lines high to this level. GND The ground (0 V) connection for your power supply. Your I²C control source must also share a common ground with this board.
• SDA Level-shifted I²C data line: HIGH is VIN, LOW is 0 V SCL Level-shifted I²C clock line: HIGH is VIN, LOW is 0 V XSHUT This pin is an active-low shutdown input; the board pulls it up to VDD to enable the sensor by default. Driving this pin low puts the sensor into hardware standby. This input is not level-shifted.
