Questions about Pixhawk4 ( SKU20068 ) from Holybro

Are the 10 pin cable supposed to be connected between FMU PWM out and one of the 3 small boards pictured?

I guess that these boards with their headers are where the servos are connected. Is this correct?

Do I have to install or splice a connector for +5 volt DC and ground in to the 10 pin cable and draw power from the BEC to the servos?

Why is there no power connectors for that on those small boards ?

At last the Pixhawk 4 gets power from the PM02 power module to POWER1.
