During module self-processing, query the MCU to set the working mode of the module and specify the I/O interface information of the corresponding function.
Check the specific I/O pins against the module silk screen and the module datasheet according to the I/O interface information you specified.
Connect the I/O interface to the corresponding functional hardware according to the required I/O interface and active low settings.
