Version: A01 Document No.: SJ-GU-TFmini-01 Page 5 of 10 Fig. 2 Measurement range schematic diagram TFmini FOV The FOV of TFmini is 2.3˚, which determines the side lengths of different detection ranges of LiDAR (the detection range is similar to a square shape). Fig.
Version: A01 Document No.: SJ-GU-TFmini-01 Communication protocol UART Baud rate 115200 Data bit 8 Stop bit 1 Parity bit 0 Page 6 of 10 Table 5 External communications 5.1 Standard Data Format of Serial Port The module data is a hexadecimal output data; each frame data is encoded with 9 bytes, including 1 distance data (Dist); each distance data has corresponding signal strength information (Strength); the frame end is the data parity bit.
Version: A01 Document No.: SJ-GU-TFmini-01 Page 7 of 10 Fig. 4 TFmini line sequence description TFmini line sequence is shown in “TF_mini line sequence description” in Fig. 4; generally, there are provided with the wiring terminals, among which, the green line corresponds to TX, the white line corresponds to RX, the red line corresponds to +5V, and the black line corresponds to GND. 6.
Version: A01 1. Document No.: SJ-GU-TFmini-01 Page 8 of 10 Product Type/ UART Control Zone 1 Product Type (product type selection): connect the appropriate LiDAR type through the TTL-USB adapter plate on the computer. As shown in the figure, TF02 produced by our company is used, for which Benewake TF02 should be chosen. 2 Serial Port (serial communication port): select the computer to identify the port number corresponding to the LiDAR.
Version: A01 Document No.: SJ-GU-TFmini-01 Page 9 of 10 FOLDER (folder unfolding): press [FOLDER] button to unfold the folder where the 2 data is saved. 4. Data Image Display Area: the upper computer draws a continuous distance measuring image based on the data received, with the vertical axis indicating the current distance measured and the horizontal axis indicating the number of valid points. 5. Real-Time Data Display Area 1 Dist (measured distance value): in the default unit of cm.
