Hi, I use one PWM servo motor MG90S (0-170 degrees) and if I turn on the ESP32-WROOM-32D, I will set 0 degrees without any problems, I will also set 170, but I always have to reset the GPIO25. The servo motor starts to rotate spontaneously. The GPIO25 is a PWM pin. On ESP32 I use wifi for webserve…

PWM problem with GPIO25 on ESP32-WROOM-32D

You are actually powering the servo through/from the ESP32 board via the USB? The ESP32's steering diode will be damaged.
