The SG90 9g Micro Servo Motor is a lightweight, low-cost actuator designed for precise angular rotation. Unlike standard continuous DC motors, the SG90 utilizes a closed-loop internal circuit with potentiometer feedback to rotate to a specific angle and actively hold that position. Its micro-sized footprint makes it the go-to component for small robotics, remote-controlled (RC) aircraft, and electronic lock systems.
✨ Key Features
- Precise Angular Control: Operates within a 0° to 180° range via position commands.
- High Power-to-Weight Ratio: Delivers up to 1.8 kg-cm of stall torque despite weighing only 9 grams.
- Seamless Compatibility: Integrates directly with Arduino libraries and other microcontrollers using standard 3-pin headers.
- Integrated Drive Electronics: Houses its own DC motor, reduction gear train, and feedback circuitry inside a compact casing.
