No, There are 4 sensors (L3G4200D ADXL345 HMC5883L BMP085) and there is not much of a description on them. It is pretty much of a gamble for me. If it works, then great. If not, then it was only $12 so it is what it is at that point. Similar sensors on sparkfun are $50 to $100.

This is the link to newegg (Shortened so it's not a mile long)
It gives me the information over i2c and I am not sure if it has a Digital Motion Processor (which is why I was going to have my arduino process it and then send it to the CRIO)
Anyways, I get it today, so when I get home, I will play with it and tell you how it goes.
As for the IMU You guys designed, I would definitely buy it for $70. Would I need it? Probably not, but it is nice to have, especially when trying to drive straight or aim a turret and have it set to a position. Would these be available to buy by the beginning of the season or at the latest, 2 weeks in? If so, sign me up!
