Hello, I'm about to buy a Red back spider robot controller (
http://robosavvy.com/store/product_info.php/products_id/1574) to control a rover 5 robot. In my project I do also have to save some data and send it via xBees so the Wireless SD shield (
http://arduino.cc/en/Main/ArduinoWirelessShield]) seemed perfect but as I'm a newbie I do not know if it will fit on my Red back spider controller ( arduino mega) so could you please enlighten me

If it won't fit do you have any other suggestions?
thanks so much!
