As the title says, the main wiki says absolutely not the F9R but doesn’t go into detail as to why. The docs are old so capabilities may have changed since the wiki was made.
My understanding is that it outputs ‘fused’ data and it wasn’t ideal at the time.
All this panda talk seems to me like the goal is to get the IMU and GPS data fused much quicker. Why not just use the F9R where the IMU is literally on the same chip?
