GY-VL53L0XV2V VL53L0X Time-of-Flight Distance Sensor Breakout Module

Descriptions:

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.
The VL53L0 uses ST’s FlightSense technology to precisely

measure how long it takes for emitted pulses of infrared laser

light to reach the nearest object and be reflected back to a

detector, so it can be considered a tiny, self-contained lidar system.

This time-of-flight (TOF) measurement enables it to accurately

determine the absolute distance to a target without the object’s

reflectance greatly influencing the measurement. 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.)
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. Our breakout board addresses

these issues, making it easier to get started using the sensor, while

keeping the overall size as small as possible.

PIN     Description

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.
