Pixhawk 6x and Companion Computer (Jeteon Orin NX): Serial connection or Ethernet?

[MJavadZallaghi]

I will have Pixhawk 6x flight computer, and J4012 Orin NX as my companion computer.

Considering I will use MRS PX4 firmware and MRS System as my aerial robot autonomy stack, what type of interface between Pixhawk 6x and Jetson Orin NX is suggested by you? Using Ethernet interface or Serial (USB) interface? Which one is compatible and tested with MRS system?

I will have also other sensors that will use probably USB as interface to companion computer for visual navigation. So it's important to figure out which interface between companion computer and flight computer is the best based on your experience.

Thanks for your comments!
