Can someone tell me if the PixHawk, when connected to the 3DR power module, or with a USB cable, have 5V on the main-out (RC) pins?
I see only about 1.2 VDC there. Is an external BEC required?

Anyone? Perhaps someone with a PixHawk can put a volt meter on the Main OUT (RC) center pins and see if there is any voltage there?
Hi Phil,
Thanks for the reply and confirming that a BEC is required.
I'd also like to know if there is any voltage found on the RC power rail when no BEC is connected.
Without a BEC connected here, I can measure about 1.2 VDC on the RC power rail (center pins).
I do have a 5.6 V Zener ready for when I connect BEC there. I'm not using servos, but will use the Zener for protection.
