TowerPro SG90 9g Micro Servo Motor (180° Rotation)
Overview:
The SG90 9g Micro Servo Motor is the world's most popular lightweight servo for hobbyists, students, and DIY makers. Offering precise $180^\circ$ angular positional control, this compact motor is perfect for beginner-to-advanced electronics projects that require controlled mechanical movement. Whether you are building an automated robot arm, a smart lock mechanism, or a pan-and-tilt sensor mount, the SG90 delivers reliable performance at a budget-friendly price.
Key Features:
- Precise $180^\circ$ Positional Control: Rotates accurately between $0^\circ$ and $180^\circ$ based on pulse-width modulation (PWM) signals.
- Ultra-Lightweight & Compact: Weighs only 9 grams, making it ideal for weight-sensitive applications like RC planes and small robotics.
- High Compatibility: Connects directly to Arduino, Raspberry Pi, ESP32, and standard RC receivers using a standard 3-pin connector.
- Complete Hardware Pack: Includes 3 distinct servo arms (horns) and mounting screws to fit various mechanical linkages.
