At $40 USD it is not cheap. There are however working examples of interfacing to the beaglebone in python. Curious if anyone has been eyeing other alternatives.
Thoughts on MinIMU-9 v2 Gyro, Accelerometer, and Compass (L3GD20 and LSM303DLHC Carrier) sensor package
the price does not seem that bad compared to similar products on sparkfun(i havent looked in-depth on this)
it would be really nice to get a IMU integrated, a compass is really nice to have on a ROV, you can easily loose track of direction when decending and in unclear water.
