Hi,
is it possible to power pixhawk via ubec from esc?
i have a hexa with 6S setup. and also more current. current can rise to 140 A here.

exact question:
if possible, make it sense to power pixhawk via an esc build in ubec?
can i use attopilot 180A current and voltage sensor with pixhawk?

alternative question:
exist an power module for pixhawk which support 6s and higher current than 90A?

this is a 90A up to 8S power module, I’m using on 6S, so far so good

You can power the Pixhawk from the servo rail with a 5.3- 5.7V BEC

this help me a little bit. so firstly while the new module is in progress, i can power the pixhawk via one of my esc BEC.

find this in pixhawk wiki.

Pin 3: power management connector current pin, accepts up to 3.3V, usually attached to 3DR power brick with 17:1 scaling[/quote]

can i connect my attopilot current & voltage sensor to this both pins without trouble. attopilot current and voltage sensor output scale is designed for 3.3V ADC.
