1M0Input(weak pull-up)Work with M1 to decide 4 working modes of module (not suspended, if notused, could be grounded).
2M1Input(weak pull-up)Work with M0 to decide 4 working modes of module (not suspended, if notused, could be grounded).
3RXDInputTTL UART inputs, connects to external (MCU, PC) TXD output pin. Can beconfigured as open-drain or pull-up input. Ground
4TXDOutputTTL UART outputs, connects to external RXD (MCU, PC) input pin. Can beconfigured as open-drain or push-pull output
5AUXOutputTo indicate module ’s working status & wakes up the external MCU. During theprocedure of self-check initialization, the pin outputs low level. Can beconfigured as push-pull output (can be suspended).
