How to connect A9G GSM +GPS module to raspberry pi ? Any articles for help?
Unfortunately, could not find any. As far as I can understand, the connection will be like the following.
Raspberry pi4 5V pin-A9G VUSB pin
Raspberry pi4 GPIO 14 (Tx)-A9G Rx
Raspberry pi4 GPIO 15 (Rx)-A9G Tx
Raspberry pi4 GND-A9G GND
Then, the respective AT commands must be sent/ pursed by a python script depending on your application.
