I'm starting a new project and I need a suggestion about the hardware to buy.
I need few more Digital Input than what the Arduino Uno can supply, so I can't use the Arduino Uno.
I need to communicate with GSM module in order to post images via HTTP POST method on my website.
Which hardware should I buy?
I was thinking to buy Arduino Due with GSM shield V2 but, even if they are electrically compatible, I read that GSM library is not supported by the arduino due.
I was thinking to use the Arduino MKR GSM 1400 but is has few digital inputs.
Which is the solution?
