Name	Direction	Function
MO	Input (weak pull-up)	Work with Ml to decide 4 working modes of module (not suspended, if not used, could be grounded).
Ml	Input (weak pull-up)	Work with MO to decide 4 working modes of module (not suspended, if not used, could be grounded).
RXD	Input	TTL UART inputs, connects to external (MCU,PC) TXD output pin. Can be configured as open-drain or pull-up input.
TXD	Output	TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output
AUX	Output	To indicate module ' s working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured as push-pull output (suspending is allowed).
VCC	Input	Power supply ： 3.3~5.5VDC
GND	Input	Ground
