Pin serial number

Pin namePin orientationPin use
1M0
Input (very weak pullup))

In conjunction with M1, the module is determined by 4 modes of operation (not dangling, if not used grounded)

2M1Input (very weak pullup)

In conjunction with M0, the module is determined by the four modes of operation (not dangling, if not used grounded).

3RXDinput

TTL serial input, connected to an external TXD output pin.

4TXDoutput

TTL serial output connected to an external RXD input pin.

5AUXoutput

Used to indicate the operating status of the module (can be suspended)

The user wakes up the external MCU and outputs a low level during power-on self-test initialization.

6VCC-

The module power supply is positive reference with a voltage range of 2.5 to 3.6V DC

7GNDinput

Module ground

8RESETinput

Module reset pin, active low
