5M0Input(pull up when it's weak)
Cooperate with M1 to determine 4 operating modes of the module(can be lifted floating, the module contains pull-up resistor)
6M1Input(pull up when it's weak)
Cooperate with M0 to determine 4 operating modes of the module(can be lifted floating, the module contains pull-up resistor)
7RXDInput
TTL serial input, connect to external TXD output pin;
8TXDOutput
TTLserial input, connect to external RXD output pin;
9AUXOutput
Used to indicate the working status of the module; the user wakes up the external MCU and outputs a low level during the power-on self-test initialization
10VCC-
Module power supply positive reference, voltage range: 2.6V ~ 5.5V DC
