Cube Orange+ vs Orange+IB

Cube Autopilot

What is the difference between the Pixhawk Cube Orange+ and the Orange+ IB?

I read somewhere that the IB version is for a specific application, which one is that?

I believe the Cube Orange+ IB has different (or less?) internal vibration damping and I believe you need a suitable use-case (logs) to get one.
I’ve never seen one myself.

I was told at an exhibition that the Orange+ IB makes sense from approx. 28" propellers and up, don’t know how reliable that is
