Preflight checklist: companion computer ✅

In this tutorial, I show you how to connect your PixHawk to both the Raspberry Pi, and an NVIDIA Jetson (a Nano in this case). This includes:

Soldering a serial cable that connects to the telemetry port (TELEM2)
Which GPIO pins you need to use
How to setup MAVProxy and its dependencies

The steps shown should also work for newer models of the PixHawk (eg, Pix32v5, Pixracer, Hex Cube). Just make sure to pay attention to the cable soldering everything else should remain the same.
