2 Its data is stable 3 It has a green power indicator that shows the working status. 4 It can monitor and maintain LIN bus device communication. 1.Specific Function Introduction: 1 The measured baud rate of the module can reach 57600bps,and the recommended maximum operating frequency is less than 20Kbps. 2 This module is just a level conversion module and does not participate in conversion analysis such as software protocols. 3 When the module is connected to the computer's COM port,the computer can receive data,but it cannot communicate with your slave device as a host.The computer's com port cannot generate the 13-bit start bit in the LIN protocol,but it can be connected to a development board such as a microcontroller.
