I am in need of a reliable gyro/accelerometer combo, that already has built-in motion processing (don't want to deal with Kalman filters in software). It seems that there are breakout boards out there (like IMU Fusion Board – ADXL345 & IMU3000), offering built-in motion processing, but the online comments sections reveal that that is not the case, or that it is rather hard to achieve. The MPU-6050 sounds more reliable, yet there is no official breakout board available yet.

• I actually only need 1 DOF as the project has just one rotation point (think of a swing). But all available boards seem to have the maximum DOF.

• Range and accuracy (resolution) are not of high priority. But i am really hoping for a noise-free signal!

• A plus would be if i could daisy-chain those boards together. If not i'll have to add another hardware piece that chains them together.

Any recommendations or comments would be appreciated! Thanks!
