Arduino compatibility Rev3 + TFT touch + GPRS

Projects General Guidance

Hi @all,

I am new to arduino and wanted to ask if I can run a Arduino Uno Rev3 with a GPRS-Shield + a TFT touch display stacked on it.

Are those components compatible?

Check the pin usages:

They both use pin 9, and potentially both use 7 and 8, depending on whether you use hardware or software serial.

:roll_eyes: =(

Thanks for your answer. Is there a "work-around" ?

Maybe another version of the arduino board can support both shields? like arduino mega?

The mega might work, but you will need to get an touch LCD that works with the megas higher pins 18-53, and the GPRS could use the regular pins. keep in mind the height of the shields you put on. They may not be able to both go on without some modifications.
