0. Introduction to TinyF

The TinyF laser ranging module is based on a D-TOF single-point laser sensor, an onboard MCU, and a housing. It features built-in sunlight rejection and anti-cover contamination algorithms, enabling accurate and rapid distance measurement. Even in extremely bright ambient light (100-190K Lux), it can accurately measure even the smallest objects, unaffected by variations in reflectivity, achieving precise ranging of 2m to 4m.

3. Main code explanation

4. Experimental Phenomena

Upload the hex program provided by the example to the microbit

Connect the wires according to the wiring diagram, plug in the battery, and turn on the switch.
Set the serial port assistant to the interface shown in the figure

After power on, the serial port assistant will print the following information
