I have a Navio2 and a older Px4flow.
When I connected the Px4Flow, but I can see the red wire (5v) is opposite of the diagram the one Navio (non-2) or the position of other red wires of other ports (serial, power, etc).
Also, I was checking a Navios diagram (I did not find diagram of Navio2).
I did not power on it yet, waiting to be sure that it is OK, or I should change the polarity of the wires.
Somebody know it?
where can I find a diagram ports of Navio2?
