Hi everyone, can you tell me why with this configuration (img attached) the DS3225MG servo doesn't work?
Do I need to add parts to the circuit?
The goal is simply to make it rotate 0-180 ° with an ESP8266. Everything works perfectly with SG90 servos...
Thanks for the help in advance.
Probably not enough power. What's the power supply specification?

Thanks for the reply.
I'm powering the servo with a power bank. Specifically one of these two:
Those power banks sound like they should have enough power for the servo. You could try using 4 x 1.2V NiMH AA batteries which aren't current limited to see if that helps.
If the servo still doesn't do anything one other possibility is that your particular servo can't tolerate a 3.3V control signal (they normally expect 5V). Can you try level shifting the control signal to see if that makes a difference? See How to interface a 3.3V output to a 5V input. – next-hack.com for many ways to interface a 3.3V signal with a 5V device.
