SparkFun Garmin LIDAR-Lite v4 Distance Measurement Sensor

SparkFun Garmin LIDAR-Lite v4 Qwiic LED Distance Measurement Sensor is a high-performance, wireless optical distance measurement sensor that doesn’t require any soldering to get started. The LIDAR-Lite Sensor features up to a 10-meter range, 1cm resolution, and requires 85mA during data acquisition. Using the I2C protocol, users can read and write to the LIDAR-Lite v4, utilizing the SparkFun Qwiic system. The LIDAR sensor requires 5V to operate but runs on 3V3 logic. With a 5V boost circuit and an easy-to-use Qwiic connector, users can power the sensor and get distance measurements over Qwiic, all with a single piece of hardware.

The SparkFun Garmin LIDAR-Lite v4 Qwiic LED Distance Measurement Sensor sends out an infrared beam and measures the time it takes to be reflected. The LIDAR-Lite v4 utilizes LEDs rather than a laser for this iteration and is inherently eye-safe under normal usage.

The built-in nRF52840 microcontroller runs a pre-loaded “out of the box” application to calculate the distance between itself and an object in front of it. The equipped nRF52840 also allows developers to create custom applications to expand on the “out of the box” functionality or connect to an external micro-controller running a custom user application.


  • 1cm Resolution
  • Measurement repeatability:
    • As measured indoors to a 90% reflective target
    • 1cm is equivalent to one standard deviation
    • Using “high accuracy” mode, with averaging:
      • +/- 1cm to 2 meters
      • +/- 2cm to 4 meters
      • +/- 5cm to 10 meters
  • Range: 5cm to 10meters (as measured from back of unit)
  • Update rate:
    • I2C = >200Hz typical
    • ANT® = up to 200Hz to a 90% target indoors at 2m in normal operating mode
  • Interface: I2C or ANT; user configurable for SPI using the Nordic SDK
  • 3.3VDC Power (operating voltage)
  • -20°C to 60°C Operating temperature
  • 940nm LED wavelength
  • 4.77° Beam divergence
  • 14.9mm Optical aperture
  • 2.8in x 1.0in x 0.9in Unit size (LxWxH)
