Input The UART_BAUD_RESET pin is used to reset the baud rate of the device. It
defaults to a high level after power-on. In any mode, the module serial port
parameters will be restored to the default 115200 if the pin is pulled down for
more than 1000ms.
Output The ACK pin is used to indicate the status of the last user data transmission.
The pin is pulled low before the transmission is started, and the pin is pulled
high after the transmission is successful.
Input/Output GPIO input/output port 0
- Module power supply positive reference voltage, voltage range
- Ground wire, connected to the power reference ground
Input/Output GPIO input/output port 1
- Reserved, directly suspended
- (PIO5 pulled low, the module is in download mode; PIO5 pulled high, the
module is in running mode)
Output The AUX pin indicates the current working status of the device. When the pin
is low, it indicates that the device is busy, and the high level indicates that the
device is idle.
