DFRobot TF-Luna ToF Micro Single-point Ranging LiDAR

The TF-Luna from Benewake is a LiDAR that determines the distance to a point by time-of-flight measurement (ToF). It measures from 0.2 to 8 m with 1 cm resolution and up to 100 times per second. The data comes via UART or I2C with 3.3 V level, the supply needs 5 V. This makes it work with Arduino, Raspberry Pi, ESP32, ESP8266 and STM32.
