Compass 3 not detected

Normaly a cube black have 3 compass, but on the screenshot of HW ID page only 2 compass are detecte. Why?

Best regards

Hey! Cube black has only 2 internal compasses. Only one compass is probed from MPU9250.

On datasheet I read:
3x accerelometer
3x Magnetometer
3x Gyroscope

On Cube Black, Magnetometer and Compass are different?

If it is normal that my cube has 2 compass it is the essential, 2 or 3 it does not matter for my project, it is a boat.


With respect to hardware, there are 3 compasses. One of the compass is disabled/not probed to feature Fast sampling.

Thanks for this information.

the 3rd compass is on the Here GPS
