I'm going to use an Intel Edison companion cpu to control the PX4 and give orders to it. I already installed everything I need on the Edison according to this guide.
Now I only need to connect it physically. so I found this - https://pixhawk.org/dev/companion_link
Which gives several methods of connecting them together. From what it says, the best method to connect both of them is by UART to UART.
So I need to make a cable that on one end connects to the TELEM2 port on the PX4, and on the other end connects somehow to the Arduino board with the Edison on it.
I tried to figure out what this table mean, but my knowledge in electronics is little, and I can't understand how this cable suppose to look like and how it suppose to connect to the arduino board. Anyone ever created such a cable?
