75 dollar IMU

Posted by Tim McMahan on February 8, 2010 at 7:51am
I haven't gotten my first Ardupiilot up and running yet.  I'm hoping to do some GPS navigate at ground level, then put it on a plane.  I'm still trying to decide what is best for me to stabilise the plane.  The simplest seems to be the FMA co-pilot system, but its also one of the more expensive, and seems somewhat limited.   An IMU seems to be the way to go, though I still; don't FULLY undrerstand them.  Do all IMU's output data the same way?  Are the Gyros and accelerometers operating similar to an RC heli rate gyro and heading and hold gyro?  
   A friend of mine linked me to a site where he's looking into FPV equipment, and Ii was looking around when I stumbled onto this 6 dof IMU for 75 bucks.  Does it work any differently than other IMU's?  If so how?

    This really only forms the basis for an IMU - ie it is the gyros and accelerometers. You will need some type of processor and software to be able to call it an IMU.
