The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 centimeters and as far as 12 meters! As with all LiDAR sensors, your effective detection distance will vary depending on lighting conditions and the reflectivity of your target object, but what makes this sensor special is its size. Measuring only 42x15x16mm, the TFMini allows you to integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders.
The TFMini is easy to power at only 5V and easy to talk to using a 3.3V UART at 115200 baud.
NOTE: The TFMini works with supply voltage of 5VDC, however, the logic level of TX and RX pins is 3.3V and is not 5V tolerant. A Logic Level Converter is recommended if connect directly to a 5V device (e.g Arduino Uno and Mega).
