BEC to Pixhawk 2.4.8 rail question

Hardware Pixhawk family
1

Hi,
I have a pixhawk 2.4.8 and would like to use the Cascade WP 2.0 to power the rail. I have seen the documentation but I have a question. The SBEC has two output wires one with the 3 wires and the other with power and ground. I am using the Pixhawk for an ardurover project. I would like to control throttle, steering, switch and differential servos from the pixhawk via a companion computer (no RF receiver). Do I connect both of them to 2 Aux pin or only one of them? Do I need the zener diode? The ESC is a Cascade esc.

thanks
P.

Good day, if you want power your pixhawk aside your pdb on the cables of your sbec you can solder a small capacitor and a zener diode…dont exceed the 5.30V.

There is a detailed explanation in the wiki

It is possible to power the pixhawk from the servo rail although it is HIGHLY recommended to do only if a zener diode is installed
