GPRS module, serial 3.3v ?

Products & Technology Shields
#1

Hello;

I got the GPRS arduino shield, I know that it was created to be used with an arduino or seeduino, anyway I found this device (GPRS module) pretty useful for my project; however I’m using a FPGA board instead arduino and I would like to know if may I connect my FPGA directly to the GPRS Module; all my FPGA ports work with 3.3v i do not if it is a risk to connect directly, any advice?
on the other hand I think would be better to have a datasheet about the GPRS board itself, I mean all is focused in arduino & seeduino microcontroller; maybe would be better to find useful this module with several digital devices.

Thank you, I’ll appreciate your advice

Regards
