Forgive me, I'm sure this is a total noob question, but I have never seen it actually addressed in any example or demo.
When using something like a MinIMU-9 board (https://www.pololu.com/product/2738/), does it matter what position you mount the board on your project? I mean, does it have to be positioned so the proper axes line up with the axes of your vehicle, or is there some calibration to set that alignment?
For a ground vehicle where I will concerned primarily with only one axis, are all axes interchangeable?
