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 (can be suspended).
