6RXD
enter

TTL serial port input, connected to the external TXD output pin; can be configured as open-drain or pull-up input, see parameter settings for details

7TXD
Output

TTL serial port output, connected to the external RXD input pin; can be configured as open-drain or push-pull output, see parameter settings for details

8AUX
Output

Used to indicate the working status of the module, the user wakes up the external MCU, and outputs low level during the power-on self-check initialization period. It can be configured as an open-drain output or push-pull output. For details, see parameter settings (can be left floating)
