The SG90 9G Micro Servo Motor is a compact rotary actuator designed for Arduino projects, RC models, robotics, and DIY electronics. It provides controlled angular movement, making it suitable for applications requiring precise positioning, such as robot arms, steering mechanisms, small robotic systems, and model aircraft.
This lightweight servo features a plastic gear mechanism and a 3-wire control connection. It operates using a PWM control signal and supports approximately 180° of rotation, depending on the specific model and control settings.
The SG90 is suitable for hobbyists, students, and electronics enthusiasts working on compact motion-control projects. Its small size makes it convenient for installations where space and weight are limited.
Product Dimensions: Approximately 23 × 12.2 × 29 mm (Length × Width × Height), excluding mounting tabs. These are typical SG90 servo body dimensions; the exact dimensions may vary slightly between manufacturers.
Weight: Approximately 9 g.
Torque: The supplied image indicates 1.5–1.7 kg·cm. Actual torque depends on the servo version and operating voltage.
The servo requires a suitable power supply and compatible PWM control signal. Avoid forcing the output shaft beyond its operating range.
