1GNDInputModule ground
2VCCInputPositive reference of module power supply, voltage range: 3.3~5.5V DC
3AUXoutputUsed to indicate the working status of the module; the user wakes up the external MCU, and the output is low during the initialization of the power-on self-test

4TXDoutputTTL serial port output, connected to external RXD input pin;
5RXDenterTTL serial port input, connected to the external TXD output pin;
6M1Input (very weak pull-up)Cooperate with M0 to determine the 4 working modes of the module (not floating, if not used, it can be grounded)
7M0Input (very weak pull-up)Cooperate with M1 to determine the 4 working modes of the module (not floating, if not used, it can be grounded)
