Can the Servo Rail provide backup power to the Cube Orange Plus FC?

[blueMoon (Sung Min Oh)]

Hello

I am using the Cube Orange Plus FC and would like to ensure that the flight controller has a reliable backup power source.

I understand that the Power1 and Power2 ports are the primary sources for power redundancy. However, I am wondering if the Servo Rail (PWM Output Rail) can also act as a backup power source in case Power1 and Power2 fail.

Specifically, I would like to know:

1. If I supply a stable 5V to the Servo Rail, will it keep the Cube Orange Plus FC running if Power1 and Power2 lose power?
2. If yes, does the Cube Orange Plus have built-in support for automatic power failover to the Servo Rail?
3. Are there any risks or limitations to using the Servo Rail as a backup power source?

I would appreciate any official documentation or technical insights regarding this topic.

Thank you!

No, the servo rail won’t power the flight controller.
