OPTICAL RANGING // 940 NM TIME-OF-FLIGHT SENSOR

ST VL53L0X Time-of-Flight Laser Ranging Breakout Board

The ST VL53L0X is a 940 nm VCSEL Time-of-Flight (ToF) laser-ranging sensor that measures absolute distance up to 2 meters regardless of target reflectance. Pure Engineering designed a compact breakout board that plugs into 3.3 V Arduino / Nucleo headers and the PUREmodules 62-mil card-edge bus.
