TowerPro SG90 9G Micro Servo Motor 180° for Arduino & Robotics

# TowerPro SG90 9G Micro Servo Motor – 180° Position Control ## Product Description The TowerPro SG90 9G Micro Servo Motor is a compact, lightweight, and versatile servo designed for robotics, Arduino projects, RC models, STEM education, and DIY electronics. Its small form factor and approximately 180° rotational movement make it suitable for applications requiring controlled angular positioning. Weighing approximately 9 grams, the SG90 is ideal for lightweight mechanisms and compact projects where space and weight are important. It uses PWM (Pulse Width Modulation) control signals to position the output shaft accurately within its operating range. The servo features a simple three-wire connection for power, ground, and signal, making it easy to integrate with Arduino boards and other compatible microcontrollers. It is commonly used in robotic arms, steering mechanisms, camera pan-and-tilt systems, model aircraft, and small automation projects. ## Key Features - Compact and lightweight 9g design - Approximately 180° angular movement - PWM-based position control - Approximate torque: 1.2 kg·cm, depending on operating conditions - Simple three-wire interface - Compatible with Arduino and other suitable microcontrollers - Suitable for robotics, RC models, and DIY electronics - Useful for educational projects and rapid prototyping ## Technical Specifications - **Brand:** TowerPro - **Model:** SG90 - **Product Type:** Micro Servo Motor - **Weight:** Approximately 9g - **Operating Voltage:** Typically 4.8V–6.0V; verify the specific product datasheet - **Rotation Range:** Approximately 180° - **Torque:** Approximately 1.2 kg·cm under specified test conditions - **Control Method:** PWM position control - **Wire Configuration:** 3-wire connection - **Red Wire:** Positive supply (VCC) - **Brown Wire:** Ground (GND) - **Orange Wire:** Signal - **Gear Type:** Typically plastic gears - **Applications:** Robotics, Arduino, RC models, automation, STEM, and DIY electronics ## Applications - Arduino and microcontroller projects - Small robotic arms and robots - RC cars, aircraft, and hobby models - Camera pan-and-tilt mechanisms - Lightweight steering and positioning systems - Educational electronics and STEM projects - DIY automation and prototyping ## Installation and Compatibility Connect the red wire to the appropriate positive supply, the brown wire to ground, and the orange wire to the compatible PWM signal output.
