Hi folks,
I'm looking for a GPS/GPRS arduino shield, ideally combined. There is so many GPS and GPRS shield out there. I need to put GPS tracker in a shoe and really have very small room. Consider the bad antenna position too. I'm just confused. Don't know which one is good :-?
So my question is do you know any good small component that can work by a weak signal? It would be great if compatible with Arduino nano.
