Debugging:

Wiring:
– Use USB to TTL serial cable, VUSB to 5V; GND to GND; AT_TX to RX; AT_RX to TX
– Use USB cable to power the board, GND to GND; AT_TX to RX; AT_RX to TX
– Use lithium battery to power the board, VBAT to 3.3-4.2V; GND to GND; AT_TX to RX; AT_RX to TX (Press power_key button for 2S)

Power on:
1. The A9G development board can be powered by lithium battery or USB.
2. The module will run automatically after 1~2S power on, and the serial port will output the information automatically. No operation is required for the whole process from power on to the development board working normally.
3. To reset, please press the Rst_Key button.
4. The module enters AT instruction mode by default.
