Connection with serial module:
About the USB cable, you can make one as below
Note: you need install driver for serial module and need switch it to 3.3V
Power supply: DC5V-18V, when you use 5V, the current need above 1A
Here we used power bank with 5V 1A output to power the SIM7080G Board
Software:
You can use SSCOM or other serial port software
Choose COM port and set BaudRate to 115200
Send AT Command
SIM7080G works with Arduino UNO.
First, you need set the baudrate to 9600( connect SIM7080G module with serial module to set it)
Send AT Command AT+IPR=9600;&W
When it shows OK, that means the BaudRate already set from 115200 to 9600
Just in case, you can choose BaudRate 9600 and send AT to test
Connection with Arduino UNO:
