When building electronics projects that sense distance or detect objects, choosing the right sensor and wiring it correctly makes all the difference. The Benewake TFmini Plus LiDAR is a compact optical ranging module that fits well into robotics, automation, UAVs, and other DIY builds. It combines simplicity with rugged design, giving hobbyists a practical way to measure distances up to 12 meters without complex camera systems.
Understanding the Benewake TFmini Plus LiDAR
The Benewake TFmini Plus LiDAR module is a small, low-power Time-of-Flight (ToF) distance sensor. It operates from 0.1 to 12 meters with stable performance and does not require heavy processing to interpret data. The module is encapsulated to meet an IP65 protection rating, making it resistant to dust and light moisture, which adds resilience for outdoor or mobile projects.
Pinout Basics for TFmini Plus
For safe and correct wiring, it’s important to know what each pin does. On a typical Benewake TFmini Plus LiDAR unit, the four wires correspond to power, communication, and ground. The red wire connects to a 5 V power supply. The white wire functions as the receive data line (RXD) in serial communication or the SDA line in I2C mode. The green wire supplies transmit data (TXD) in UART or the clock signal (SCL) for I2C connections. The black wire must be connected to ground to complete the power circuit.
Properly matching the TXD line from the sensor to the RX input on a microcontroller like Arduino or ESP32, and vice versa, ensures reliable data flow. Keeping the connecting cable short helps maintain signal integrity, especially when using UART at the default baud rate of 115200.
Choosing the Right Connection Mode
You can choose between UART and I2C interfaces depending on your board and project needs. UART works well for direct serial connections and is easy for quick data reads. I2C may be preferred when you have multiple devices on the same bus, but it requires correct address configuration in software.
Conclusion
The Benewake TFmini Plus LiDAR is practical for makers who need a compact distance sensor that is easy to connect and versatile to use. Understanding its pinout and wiring tips helps you get useful readings without guesswork. Whether your project uses an Arduino, Raspberry Pi, or another controller, start with correct connections and simple code examples. Ready to integrate reliable Benewake LiDAR into your next build?
