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

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

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)

Module power supply positive reference, voltage range: 2.3V ~ 5.5V DC
