SG90 9g Micro Servo Motor – Product Description

The SG90 9g Micro Servo Motor is a compact, lightweight, and reliable actuator designed for precise angular positioning and motion control in a wide range of electronic and robotic applications. Weighing only approximately 9 grams, this servo motor is ideal for projects where space and weight are critical considerations.

The SG90 uses a standard PWM (Pulse Width Modulation) control signal, making it compatible with popular development platforms such as Arduino, Raspberry Pi, ESP32, STM32, and other microcontrollers. It can rotate to a specific angle within its operating range, allowing accurate control of mechanical movements in robotics, automation systems, RC models, and educational projects.

Built with a durable transparent blue housing, the servo features an integrated gearbox and motor assembly that deliver smooth and responsive operation. Its compact design includes mounting tabs for easy installation and secure attachment to project frames and structures. The three-wire interface simplifies wiring, with dedicated connections for power, ground, and control signal.

The SG90 is widely used by hobbyists, students, engineers, and makers due to its affordability, ease of use, and dependable performance. Whether controlling robotic arms, steering mechanisms, sensor platforms, automated doors, or DIY smart devices, the SG90 provides an effective solution for precise motion control.
