Hello,
I saw (can't remember where) somebody mounting the board on the chassis frame sideways (viz. z and y axis permuted).
Is that setup OK and what are the implications in software configuration ?
Thanks

Thanks a lot for the info. I was afraid some sensors were required to be in a defined orientation.
@Marc,
We don't talk about this on the copter wiki but it's briefly mentioned on the antenna tracker wiki (because it's very common to mount an APM or Pixhawk in a non-standard orientation on an antenna tracker).
Setting the AHRS_ORIENTATION will take care of rotating all the internal sensors (gyro, accels, compass). If you're using an external compass (i.e. a GPS/Compass module) then the orientation of that external compass is unrelated/unchanged. I.e. if you're using a 3dr GPS/Compass module you should still mount it with the white arrow pointing towards the front of the vehicle regardless of what the AHRS_ORIENTATION was set to.
Marc, AHRS_ORIENTATION is the parameter that tells the code how your flight controller is positioned. I have mine rolled to the right 90 degrees and all is good
