Sparkfun LIDAR-Lite v3

Sparkfun LIDAR-Lite v3
Compact distance sensor from Garmin™. It is ideal for use in places where space is limited or the least possible weight is required (drones, robots, remote control carts).

This user-friendly 40m laser-based optical sensor has all the important features that made the LIDAR-Lite v2 famous. It is small, light and has a very low power consumption, less than 130 mA during a single measurement. It is easily adjustable, so you can adjust the accuracy, distance and measurement time.
