Dear Sirs, has anyone used such an external sensor of IMU together with Pixhawk board?

Hello,

Currently we don’t have interface to accept other AHRS, but that something that will come !
Those sensor that you are mentioning are the same as in the pixhawk : MPU6050 but with a processor to filter it. The Madgwick and Mahony filter have been beaten from sometime already ! I pretty sure that our EKF is better in many aspect that those filter, but I would be interested in testing both on a copter or plane to do a fair comparison.
