user7028: if I solder the jumper pads on the adafruit cc3000 for use with the Arduino Mega will it still work fine with the Uno?

user6959: This module is designed to be "plug in and go" without access to anything except the connector pads at the board edge. While there are a number of pads on the face of the board these are for "experts only" access and are unneeded for normal operation. 
The only soldering required should be the addition of a 9 pin row of pins to allow the CC3000 module to be plugged into a solderless breadboard or a socket. If this is all you do then the module will work directly and interchangeably with  Arduino Uno, Leonardo/Micro & Mega. These are the only Arduino versions that a full library is available for so far. ADAFruit promise more versions will be supported "sometime".
