Hello everyone. I am a bit confused about the difference between the sensors on the vibration damped IMU board and the main FMU board on the Pixhawk.

They both have the MS5611 barometer, the MPU9250 containing the accelerometer and gyro. In addition, the IMU board has the LSM303D accelerometer/magnetometer and the L3GD20 gyro.

My question is, are all those sets of sensors work in tandem? For example, does the pixhawk receive the data from the 3 accelerometers and combines them in some way or discards those who are not accurate?
