Servo motor connection Pixhawk 6X

Hardware Pixhawk family
1

Hi,
I am trying to connect a servo motor that i can activate via my transmitter whenever i want. I know that Pixhawk 6X (I/O PWM OUT) and (FMU PWM OUT) rails have no power. The only pinout that has power is RCIN. Fortunately, I am not using that pin. I am using telem3 for transmitter input.

My question is how can I configure that pin as an output to activate the servo motor? Is it possible?

I have another solution, but I am scared to burn the board:
I am using the power module PM02D. and I have a small BEC laying around that can output 5V. So i was planning to power the whole rail (I/O PWM OUT) and (FMU PWM OUT) of the pixhawk and use any pin to power the servo motor. But I am still not 100% sure how to configure it.
I have a channel that i am not using ‘SE - RadioMaster Boxer’

Can you lead me which is better to do and how to the configuration side?

Note that I am already using FMU PWM OUT pins for ESCs (i am esc telemetry)
Thank you

Any guidance or ideas please?

the rails are not powered by itself as far as i know.. use a BEC, not the RCin pin..

Are you sure that would be safe to do, according to my setup? Again i am just scared to burn the pixhawk.

For anyone that have the same setup as mine, getting power from PM02D to BEC and use the power from BEC to power the rail of pixhawk 6X is sufficient. You will connect the servo motor on any pwm output and activate the function on that channel, then everything works out.

That’s quite literally how it’s supposed to work.

Just check the manual from the PX6X.. I use the PX6C almost the same setup..
