Page 4: Laser Safety Information
TFA300 series LiDAR. Measuring principle TFA300 series is a typical Pulse Time of Flight (PToF) sensor. TFA300 series emits a narrow pulse laser, which is collimated by the transmitting lens, which enters the receiving system after being reflected by the measured target and is focused on the APD detector by the receiving lens. -

4. Device Installation This section introduces the mechanical installation and connection information of TFA300 series LiDAR. Mechanical installation TFA300 The TFA300 has an IP67 waterproof housing. It is recommended to directly expose the front window of the TFA300 to the air for use. Do not add an additional transparent housing to cover the window, as this may cause crosstalk due to multiple reflections and affect the distance measurement performance. -
Page 8: Connector
Excessive spacing may cause optical crosstalk, which could compromise ranging performance. The TFA300 series utilizes a laser source with a central wavelength of 905 nm. It is recommended to use materials with a transmittance greater than 90% at 905 nm to minimize the impact of laser energy loss on ranging performance. -

Parity None Baud rate can be set to 9600, 14400, 19200, 38400, 56000, 57600, 115200, 128000, 230400, 256000, 460800, 500000, 512000, 600000, 750000, and 921600. If other value were set, TFA300 series will set it to 115200. Data Frame Each data frame under the UART interface contains distance and signal strength and consists of 9 bytes of hexadecimal values. -
Page 11: Can Communication
- Received Frames: Supports both Standard and Extended Frames The CAN interface baud rate setting only supports commonly used baud rates: 1000kps, 500kps, 250kps, 125kps, 100kps, 50kps, 20kps. If other values are set, the TFA300 series will set it to 1000kps. Data Frame Data frames under the CAN interface consist of 6 bytes of hexadecimal values, containing measured distance and signal strength, with the remaining bytes reserved. -

Page 14: Command Editing
Important: After modifying one or more parameters via configuration commands, always send the "Save Current Configuration" command to write the changes to the device. Otherwise, parameters will revert to the last saved values upon re-powering. Command editing This section describes the Command Channel of TFA300 which is used to read and set TFA300’s working parameters.
