3AUXOutput

      For user to wakes up the external MCU and it outputs low level during power-on
self-check initialization; (can be left floating)

4TXDOutput


TTL UART outputs, connects to external (MCU, PC) RXD input pin.

5RXDInput

TTL UART inputs, connects to external (MCU, PC) RXD output pin.

6M1Input(weak pull-up)


Work with M0 to decide 4 working modes of module (not suspended, if not used, could be grounded).)

7M0Input(weak pull-up)

Work with M1 to decide 4 working modes of module (not suspended, if not used, could be grounded).
