Compass Orientation?

[stefymtb (step)]

For my new wing i have fitted a HGLRC M100 gps+magnetometer module.

HGLRC M100+5883

If i direct the gps antenna to the sky, the compass should be on 180 roll
What if it is also yaw270 rotated? Is it still 270 or what?

I am doing this because i can not get right direction from the compass. Is is always about, plus or minus, 90/100° off with auto orientation and no 180 roll set because i am not sure about it.

Board is rotated yaw 270 also, if it matters. It’s a SB F405 wing.

You can cross-check the compass orientation by connecting the aircraft to the mission planner and displaying mx, my and mz in the tuning window:

The Wiki (Advanced Compass Setup — Plane documentation) describes how the spatial components change at different attitudes when compassorientation is correct.
