Benewake TFmini Plus Laser Level Distance Sensor Lidar Range Finder | Waterproof IP65 UART Anti-dust 12m 1000Hz Small-size Low-power-consumption LiDAR Module for Arduino Raspberry Pi STM32

I learned a lot on these LiDAR units from Benewake. The TF Mini Plus is a 4 pin interface, capable of Serial or I2C communication. Default is Serial, but if you want to switch to I2C, follow these steps: 1. download the GUI program from Benewake. This works on PC only 2. connect the TF Mini Plus to a TTL to USB converter 3. Plug into USB port of computer 4. run the GUI program and select the COM port/BAUD 5. So I switched to I2C using @snoozer sequence: 6. Send command 5A 05 0A 01 6A 7. Send command 5A 04 11 6F (however not sure this step did anything) Now it will be in I2C mode, but the access to the GUI program is unavailable until you switch it back to Serial mode.

Great value, works well, I put on a moving vehicle which was rattling around and it worked okay. The only thing I would mention to be aware of is that there are sometimes noisy values generated in the readings, so you need to filter the noisy values which are obviously outside of the normal range of values that it produces. Simple if statement less than huge noisy value, in C or python.

worked as intended, no issues with purchase

Using as altitude range finder on autonomous model airplane during landings. Good product.

Works well but would have been better with additional mounting points.
