20	M0	Input (very weak pull-up)	Cooperate with M1 to determine the 4 working modes of the module (cannot be left floating, can be grounded if not used)
21	M1	Input (very weak pull-up)	Cooperate with M0 to determine the 4 working modes of the module (cannot be left floating, can be grounded if not used)
22	RXD	Input	TTL serial port input, connected to the external TXD output pin;
23	TXD	output	TTL serial port output, connected to the external RXD input pin;
24	AUX	output	Used to indicate the working status of the module;
