SG90 MICRO SERVO MOTOR 

The SG90 Micro Servo Motor is a compact, lightweight servo designed for precise position control with a rotational range of 0°–180°. Combining a DC motor, gear train, potentiometer, and control circuitry in a small package, it is widely used in robotics, RC vehicles, pan-tilt camera systems, automation, and educational electronics projects.

Controlled via PWM (Pulse Width Modulation) signals from microcontrollers like Arduino, ESP32, ESP8266, or Raspberry Pi, the servo interprets the pulse width to rotate the shaft to the desired angle. The built-in potentiometer provides real-time feedback, ensuring accurate positioning, while the plastic gears enable smooth and efficient movement (metal gear variants are available for higher torque applications).

The SG90 operates at 4.8–6 V DC, delivering a stall torque of approximately 1.8 kg·cm and a speed of ~0.1 sec/60°, making it suitable for lightweight robotics and small actuator applications. Its standard 3-pin connector (VCC, GND, PWM) allows easy integration with development boards and control systems.

This versatile micro servo motor is ideal for robotic arms, pan-tilt camera modules, RC vehicles, educational kits, DIY electronics, and compact automation projects requiring reliable and precise motion control.

SG90 Micro Servo Motor is a compact, lightweight, and versatile servo motor designed for precise angular position control in a wide range of electronics, robotics, and automation projects. It is commonly used in applications where controlled movement and accurate positioning are required. The motor can be controlled by sending PWM signals from microcontrollers and development boards such as Arduino, ESP32, Raspberry Pi, and other compatible control systems.

The SG90 features a small and lightweight design, making it easy to integrate into compact robotic mechanisms and DIY projects. It is commonly used for controlling robotic arms, robot car mechanisms, sensor scanning systems, camera pan-and-tilt platforms, automatic doors, grippers, and other moving parts. The servo typically provides approximately 180-degree rotational movement, allowing users to control the shaft position according to the programmed input signal.

The SG90 Micro Servo Motor is easy to operate and is suitable for beginners as well as experienced electronics enthusiasts. It is widely used in educational projects, STEM learning, robotics experiments, automation systems, and prototyping applications. Its compact size, simple control method, and ease of integration make it an excellent choice for students, hobbyists, makers, and engineers working on DIY electronics and robotic projects.

The motor is generally operated using three connections: power, ground, and signal. The signal wire receives PWM control pulses from the microcontroller, allowing the servo shaft to move to the desired position. The SG90 Micro Servo Motor is an affordable and practical solution for projects requiring controlled mechanical movement and position adjustment.
