I want to connect servo and flight controller. I think 5 V is not enough for the servo motor. How can I connect it.
FC : Matek Slim
Servo : PowerHD WP23KG
If you look to the datasheet of the servo it works from 4.8V up to 6.0V. So in general it is possible to work with just 5 V. But this depends on your application as the maximum force is lower on lower voltage.
If you need the maximum power at 6V you have to connect just the servo signal line and GND to the FC and additional the servo power line and GND to a seperate true 6V source.
thank you servo was broken. it is why it did not worked
