- It can be used in a wide range of IoT applications for home automation, industrial wireless control, wearable electronics, wireless location-aware devices, wireless location system signals and other IoT applications, making it ideal for IoT applications.
- This a9g board has GPS function,with GPS passive antenna. But its GPS function is not good. If you need gps module, I recommend bn-180 gps, https://www.amazon.com/dp/B078Y4XZN9
- You need an external MCU or AVR to send AT commands and control the board, or to make your own firmware for the board itself
- You should use it with cp2102 serial module. The connection between A9G board and CP2102 module is RX to TX, TX to RX, GND to GND. Then you connect USB interface to your computer's USB interface (it need to be 5V),and open the IDE, you will see COM port. There is no need to choose board. You just need to open the serial monitor window and choose 115200 baud, then will see the information, make a call and send message by command.
