The Tower Pro SG90 is a compact and lightweight 9g micro servo designed for Arduino, Raspberry Pi, robotics, RC vehicles, STEM projects, and motion control applications.
- Lightweight 9g micro servo design
- ~180° positional rotation control
- Compatible with Arduino Servo library
- Standard 3-wire PWM control interface
- Includes multiple servo horn attachments
Quick Start
1
Connect power
Connect red to 5V and brown to GND.
2
Connect signal wire
Connect the orange signal wire to a PWM pin.
3
Install Servo library
Use the built-in Arduino Servo library.
4
Control position
Use servo.write(angle) to move the servo.
Please note: For best reliability, power the SG90 from a dedicated 5V supply rather than directly from the Arduino 5V pin under heavy load.
Every servo is manually tested before dispatch to ensure proper operation. Each unit undergoes two full-range sweeps from 0° to 180°, followed by rapid response testing through both 0° → 90° → 0° and 0° → 180° → 0° movement cycles to verify smooth movement, positioning accuracy, and reliability.

Common Questions
Can I use this with Arduino?
Yes, the SG90 works perfectly with Arduino using the Servo library.
Does it rotate continuously?
No, this is a positional servo with approximately 180° rotation.
Can I power it directly from Arduino?
Yes for light testing, but a dedicated 5V supply is recommended.
