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 (3.3v-4.2)V; GND to GND;AT_TX to RX; AT_RX to TX(Press power_key button for 2S)
Power on:
- The A9G development board can be powered by lithium battery or USB.
- 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.
- To reset, please press the Rst_Key button.
- The module enters AT instruction mode by default.
