A few months ago I make an autonomous rover with GPS and some distance sensors. I want to improve the hardware because I got a lot of problems with the wires from the distance sensors as well as with the GPS.
So I thought buying some arduino shields. I thought using the adafruit motorshield, gpsshield also from adafruit and the xbee shield.
But how do I know if they are compatible with each other?
PS: I was thincking to use a arduino mega R3.
