The LIDAR-Lite v4 Qwiic from GARMIN is a high-performance, wireless optical distance measurement sensor that doesn't require any soldering to get started. This is the ideal solution for drone, robot, IoT, or unmanned vehicle operations when space is tight and power is limited. This sensor has up to a 10 meter range, 1cm resolution, and requires 85mA during data acquisition. The user can read and write to the LIDAR-Lite v4 using the I2C protocol.
The LIDAR sensor requires 5V to operate but runs on 3V3 logic. With a 5V boost circuit and an easy-to-use Qwiic connector you can power the sensor and get distance measurements over Qwiic all with a single piece of hardware.
Note: The I2C address of the Qwiic LIDAR-Lite v4 is 0x62 and is software-configurable to any address. A multiplexer/Mux is required to communicate to multiple Qwiic LIDAR-Lite v4 sensors on a single bus. If you need to use more than one Qwiic LIDAR-Lite v4 sensor consider using the Qwiic Mux Breakout.
- Resolution: 1cm
- Measurement repeatability:
- As measured indoors to a 90% reflective target
- 1cm is equivalent to one standard deviation
