The BDD 9G Micro Servo SG90 is a compact, lightweight, and highly reliable 180-degree analog servo motor designed for precision motion control in electronics, robotics, and RC applications. Known for its smooth operation, fast response time, and excellent torque-to-size ratio, this servo is a staple component for both beginners and advanced makers.
With a wide operating voltage range and standard control interface, the SG90 servo integrates seamlessly with Arduino, Raspberry Pi, ESP32, RC receivers, and other microcontroller platforms.
Product Overview
This 9g micro servo offers accurate angular positioning across a full 180 rotation ( 90 ), making it ideal for applications requiring controlled movement rather than continuous rotation. Its fast response time and dependable torque allow it to drive small mechanical loads with precision.
The servo uses PWM (Pulse Width Modulation) control, enabling smooth and repeatable positioning. Its compact form factor allows installation in tight spaces while still delivering reliable mechanical performance.
