The TF Mini LiDAR is an unidirectional laser range finder based upon time-of-flight (ToF) technology. It consists of special optical and electronic devices, which integrates adaptive algorithm for indoor and outdoor application environment. It has tiny body and high performance in distance measurement.
The laser sensor can be used as a distance-measuring tool to detect the distance from it to obstacles. It can also be used as an eye of a robot; it provides distance information for robotic safe avoidance and route selection. It supports for system automation in a variety of machine control scenarios. Because of its small size, light weight and low power consumption, it is also suitable for altitude hold quad-copters and terrain following.

TF Mini's maximum detection distance is 12 meters. TF Mini also supports 100Hz sampling resolution, within 6 meters, its accuracy is within 4cm, 6~12 meters, accuracy within 6 cm. FOV of 2.3 degree. Its anti-interference is strong, and can work in outdoor light; the overall weight is 4.7g.
Measurement range schematic diagram
TF Mini LiDAR adopts UART (TTL) communication interface, can supplied by standard 5V, and its average power consumption is 0.6w. It can be compatible with a variety of Arduino controllers. With the DFRobot Gravity IO Expansion Shield, Arduino can be plugged in directly without additional wiring.
It can be easily integrated into the system when used with the Arduino library developed by DFRobot.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- LiDAR
- A sensing method that uses laser light to measure distance and build a 3D picture of the surroundings. It matters for robotics and autonomous systems because LiDAR data can help with mapping, navigation and obstacle detection.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
