ESP32 Starter Kit
Control Principle: The rotation angle is controlled via duty cycle of PWM. Theoretically, standard PWM cycle is
20ms(50Hz), so pulse width should distribute within 1ms~2ms. However, the actual pulse width reaches 0.5ms~2.5ms,
which corresponds to 0°180°. Pay attention that, for the same signal, the rotation angle may vary from servo brands.
