Hi, on my pixhawk quadcopter project, i received a broken power module, and i was wondering, is it possible to power the pixhawk using a BEC inside the ESC in the servo rail by itself? And if so, what would be the risks without a zener diode connected? I read that it prevents the pixhawk from rebooting, but are there other risks? I really don’t want to fry the pixhawk.
My setup doesn’t have any servo motors puling current from the servo rail.
If this is not a safe way to power the pixhawk, are there other ways without using a power module?
You can connect without the zener diode, the only problem is the overvoltage protection that you’ll not have.
Personally, it depends if you trust the components that you are using, and if you going to use without a protection circuit for a long time.
Is there a pinout for the Pixhawk power moduke that shows pwr and grnd? I want to add a secondary source of power to the PH from a BEC (SKU: BEC-5V6A-R1), which pins are to be used ?
