Gorillacell Module 069: Servo Motor
Table of Contents
Servo Motor, or Servo, is a rotary actuator that integrates a motor, control circuit, and positional feedback system to achieve precise control of angular position. It operates through a Pulse Width Modulated (PWM) signal sent to its control wire (usually orange). The PWM signal defines the rotation angle — the minimum pulse width corresponds to 0°, the maximum pulse width corresponds to 180°, and the signal typically repeats every 20 milliseconds.
The Gorillacell ESP32 Development Kit includes one (1) MG90S Servo Motor module, ideal for robotic arms, pan-tilt mechanisms, and other angle-controlled applications.
