VL53L0X ToF 940nm Laser Distance Sensor Module

The VL53L0X V2 Time-of-Flight (ToF) laser distance measuring sensor module is a state-of-the-art solution for precise and reliable distance measurements. It features an embedded eye-safe infrared laser, advanced filtering capabilities, and a high-speed photon detection array, all of which combine to offer enhanced ToF performance in a variety of applications. This fully integrated sensor delivers high-speed, accurate distance measurements over extended ranges, making it a powerful tool for both professional and hobbyist use.

The VL53L0X V2 is compact, measuring just 1in × 0.43in and weighing only 0.35oz, making it ideal for integration into space-constrained projects. Despite its small size, it provides exceptional performance with an effective measurement range of up to 2 meters.

The sensor’s advanced ToF capabilities extend beyond basic measurement functions. The 940nm VCSEL (Vertical Cavity Surface Emitting Laser) emitter is completely invisible to the human eye, ensuring safety while still delivering long-range and precise results. Coupled with infrared filters, it offers better immunity to ambient light and improved robustness to optical cross-talk, even in challenging environments.

Hardware Overview

PinMap

VDD	Regulated 2.8V output. Provides up to 150mA to power external components. Can be used as 2.8V input if VIN is disconnected.
VIN	Main power supply input (2.6V to 5.5V). Powers the I2C level shifters for SCL and SDA lines.
GND	Ground connection (0V). The I2C control source must share a common ground with this board.
SDA	Level-shifted I2C data line. High is VIN, low is 0V.
SCL	Level-shifted I2C clock line. High is VIN, low is 0V.
XSHUT	Low active shutdown input. Defaults to high (VDD) to enable the sensor. Driving it low puts the sensor into hardware standby. Not level-shifted.
GPIO1	Digital output. Open-drain interrupt output.
