A Servo Driver is a control module or circuit designed to operate servo motors. It generates PWM (Pulse Width Modulation) signals to control the angle, speed, or position of servos. Servo drivers are widely used in robotics, robotic arms, RC vehicles, drones, and automation systems.
🔹 Main Functions
-
Generates PWM signals for servo position control
-
Controls multiple servos simultaneously
-
Reduces processing load on the main controller (e.g., Arduino or other microcontrollers)
-
Provides stable power supply for connected servos (some models include built-in regulators)
🔹 Common Specifications
-
Supports 1–16 or more servo channels (model dependent)
-
Operating voltage typically 5V–7.4V
-
Communication via I2C, UART, or direct PWM
-
Typical servo rotation range: 0–180 degrees (servo dependent)
-
Some models support high-resolution control (e.g., 12-bit PWM)
🔹 Typical Applications
-
Small industrial robotic arms
-
Quadruped or hexapod robots
-
Camera pan-tilt systems
-
Automated opening/closing mechanisms
🔹 Advantages
-
Easy multi-servo control
-
Precise and stable motion control
-
Simplifies overall system wiring and programming
