9 PD3 Input Working mode switching pin. When the pull-down time is longer than 500ms,
the working mode is switched.
10 PE2 Input UART_BAUD_RESET pin is used to reset the device baud rate. The power-on
default is high level. In any mode, if this pin is pulled lower for more than
1000ms, the serial port parameters of the module will be restored to the default
115200.
11 PE0 Output ACK pin is used to indicate the last user data transmission status. This pin is
pulled low before the transmission is started, and the pin is pulled high after the
transmission is successful.
12 PE3(GPIO0) Input/Outpu
t GPIO input/output port 0
13 VCC - Module power supply positive reference voltage, voltage range
14 GND - Ground, connected to power supply reference ground

18 PA7 Output AUX pin indicates the current working status of the device. When the pin is
low level, it indicates that the device is busy, and high level indicates that the
device is idle.
