I want to communicate with SIM7600EI 4G LTE High-Speed Modem GPS/GNSS IoT board Raspberry Pi Compatible board using Arduino using AT commands but I am not able to do it, the reason can be the wrong rx and tx pins (I am able to communicate through AT commands using USB cable but want is using Arduino
Does it say it is compatible with Arduino?
WARNING: Raspberry Pi is 3.3v, so you have to only supply 3.3v logic to the board.
Here is a Raspberry Pi pinout.
yes it is arduino compatible
It neither knows nor cares what board you use - all it sees is signals arriving on its pins.
So, as long as you get those signals right, it will work - irrespective of what you use to create those signals.
So the first thing to do is to find the documentation for the board, and find out what it needs.
And what it generates in response.
Where did you get it? Can they not help you - with documentation, etc?
Or what about the manufacturer? It says "Parry Technology" on it - have you contacted them?
