ST VL53L1X 4-Meter Time-of-Flight Laser Ranging Sensor
The ST VL53L1X is a third-generation FlightSense Time-of-Flight laser-ranging sensor that extends absolute distance measurement up to 4 meters at ranging rates up to 50 Hz. It integrates a 940 nm invisible laser, a physical infrared filter, and a programmable 16x16 SPAD receiving array.
Architecture & Technical Specifications
Hardware Architecture & Features
- Miniature reflowable optical module (4.9 x 2.5 x 1.56 mm) with integrated 940 nm Class 1 VCSEL.
- 4 cm to 400 cm absolute ranging distance independent of target color and surface reflectance.
- Programmable region-of-interest (ROI) on the 16x16 SPAD receiving array to narrow the field of view (15 to 27 degrees).
Firmware, Software & Integration
- I2C interface (up to 400 kHz) for ranging control, ROI selection, and telemetry.
- Supported by the Pure Engineering VL53L1X Breakout Board and PUREmodules ecosystem.
