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.
The whole project will consist of ~25 sensors, that will all be connected to a desktop computer. I want to avoid having to do the heavy Kalman filtering for all sensors in software on the computer. Therefore i am looking for a sensor-board that already integrates the filtering.
DOF: 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: >= 150 degree/second
Frequency Response: >= 100 Hz
Noise: I am really hoping for a quite noise-free signal, to avoid heavy interpolation-filters later on (on the desktop computer)
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!
EDIT: I found this MPU-6050 breakout board at drotek.fr, looking for some experience reports now.
