If you’re working with compact range sensors, the TFmini Plus from Benewake is a versatile LiDAR module that combines ToF distance measurement with simple connectivity. Understanding its pin layout helps integrate it into robotics projects, automation systems, or smart devices with confidence.

Overview of TFmini Plus Pins and Connections
The TFmini Plus has a four-wire connector that handles both power and data communication. Each wire has a specific function and color reference, making the wiring straightforward once you know what each line does. The red wire provides power, the black wire is ground, and the two middle wires handle data communication. This connection uses a small JST 1.25-4P style plug. If your project requires a longer reach, the cable can be extended, though keeping the total length below about one meter helps maintain signal stability.
In terms of function, the red wire delivers five volts to the module from your controller or external supply. The first data wire serves as either the RX line for serial input or the SDA line for I2C communication, while the second data wire acts as the TX output for UART or the SCL line for I2C clock signals. The black wire completes the circuit by providing ground. The TFmini Plus supports both UART and I2C communication, giving flexibility depending on your system. By default, it uses a 115200 baud serial configuration, which is simple to interface with microcontrollers like Arduino or Raspberry Pi. Switching between UART and I2C is usually done via command, allowing the module to output distance data in the preferred format.
This configuration makes it easy to power the sensor and capture precise distance measurements. Beginners often start with UART to quickly see data flow and then explore I2C for lower pin usage or bus-style communication. The module’s compact design and reliable performance make it suitable for a wide range of applications, from small robotics to interactive devices.
