This sensor is a carrier/breakout board for ST’s VL53L1X laser-ranging sensor, which offers fast and accurate ranging up to 4 m. It uses the time of flight (ToF) of invisible, eye-safe laser pulses to measure absolute distances independent of ambient lighting conditions and target characteristics like color, shape, and texture (though these things will affect the maximum range). The VL53L1X also features a programmable region of interest (ROI), so the full field of view can be reduced or divided into multiple zones. Distance measurements can be read through a digital I²C interface. The board includes a 2.8 V linear regulator and level-shifters that allow it to work over an input voltage range of 2.6 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perf boards.


Features and specifications:

  • Dimensions: 0.5″ × 0.7″ × 0.085″ (13 mm × 18 mm × 2 mm)

  • Weight without header pins: 0.5 g (0.02 oz)

  • Operating voltage: 2.6 V to 5.5 V

  • Supply current: ~15 mA (typical average during active ranging at max sampling rate)

    • Varies with configuration, target, and environment; peak current can reach 40 mA

  • Fast and accurate ranging with three distance mode options:

    • Short: up to ~130 cm, 50 Hz max sampling rate; this mode is the most immune to interference from ambient light

    • Medium: up to ~300 cm in the dark, 30 Hz max sampling rate

    • Long: up to 400 cm in the dark, 30 Hz max sampling rate

  • Minimum range: 4 cm (objects under this range are detected, but measurements are not accurate)

  • Emitter: 940 nm invisible Class 1 VCSEL (vertical-cavity surface-emitting laser) – eye-safe

  • Detector: 16×16 SPAD (single photon avalanche diode) receiving array with integrated lens

    • Typical full field of view (FoV): 27°

    • Programmable region of interest (ROI) size on the receiving array, allowing the sensor FoV to be reduced

    • Programmable ROI position on the receiving array, allowing multizone operation control from the host

  • Configurable detection interrupt thresholds for implementing autonomous low-power presence detection:

    • target closer than threshold

    • target farther than threshold

    • target within a distance window

    • target outside of distance window

    • no target

  • Output format (I²C): 16-bit distance reading (in millimeters)
