VL53L1CX
Overview
The VL53L1CX is a long-range Time-of-Flight (ToF) sensor based on STMicroelectronics FlightSense technology, capable of measuring distances up to 400 cm. It integrates a 940 nm Class 1 laser emitter, a SPAD receiving array with an integrated lens, and an internal microcontroller that handles advanced digital firmware for distance calculations. This sensor supports multi-zone operation and a programmable region of interest (ROI), allowing for precise spatial awareness in compact designs.
Why Choose This Part
The VL53L1CX offers a significant range increase to 4m while remaining pin-to-pin compatible with the earlier VL53L0X sensor. Its programmable ROI allows users to narrow the field of view or create custom detection zones, providing better performance in applications with specific spatial constraints. Integrated firmware reduces host processing overhead by delivering calibrated distance data directly over an I2C interface.
Applications
Key Specifications
Getting Started
Start development using the P-NUCLEO-53L1A1 evaluation kit which includes an STM32F401RE Nucleo board and a VL53L1 expansion board. STMicroelectronics provides the STSW-IMG007 (X-CUBE-TOF1) software expansion pack for the STM32Cube environment, containing drivers and example code. Ensure the sensor is supplied between 2.6V and 3.5V and utilize the XSHUT pin for hardware standby to minimize power consumption when not in use.
