The ESP32 chips have outputs that work with 3.3V. The servos require 5V as operating voltage (this is not a problem that is also present at the ESP, or comes from an external power supply). However, they also require the control signal as a 5V signal.

It is therefore not certain that a servo with the 3.3V of the ESP can be reliably controlled.

There are level converters for that.

As I said, you can try it without a level converter.

I have found that with a neopixel LED (also requires 5V) it runs on the ESP32, but in the meantime there have already been disturbances.

Here’s all you need, or you already have everything you need. The rest is here
