Product Description
How Does The TFmini Click Board™ Work?
The TFmini Click Board™ simplifies the interface of the TFmini LiDAR module with the host MCU. This Click board™ represents a small PCB connected to the mikroBUS™ socket like any other Click board™, with a 1x4 1.25mm pitch connector used for the TFmini LiDAR sensor connection. Each of the connector pins corresponds to a pin of the TFmini LiDAR sensor, allowing easy pin access and manipulation while retaining a perfect connection quality at all times.

The TFmini Click Board™ allows users to upgrade their projects with a sensor capable of measuring the distance to an object, where different measurement ranges are possible to achieve. As with all LiDAR sensors, the effective detection distance will vary depending on lighting conditions and the reflectivity of your target object. These sensors come with an IP65 enclosure rating, 100Hz frame rate, and 70Klux ambient light immunity and are suitable for various industrial environments like pedestrian detection, vehicle testing, and altitude.
The TFmini Click Board™ provides the possibility of using both UART and I2C interfaces, with commonly used UART RX and TX pins as its default communication protocol operating at 115200bps by default configuration to transmit and exchange data with the host MCU. The selection can be made by positioning the SMD switch labelled as COMM SEL to an appropriate position. Note that all the switch positions must be on the same side, or the Click board™ may become unresponsive.
This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VIO SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
