SG90 Micro Servo Motor 9g

The SG90 Micro Servo is the most widely used small-scale servo motor in the maker and hobbyist community, prized for its compact size, light weight, and reliable performance across robotics, RC models, and embedded automation projects. Weighing just 9 grams and housing a plastic gear train driven by a compact DC motor, this servo delivers precise positional control for any project requiring controlled rotational movement without the bulk of a standard-size servo.

Operating via the industry-standard PWM (Pulse Width Modulation) control signal, the SG90 rotates approximately 180° (90° in each direction from centre) based on pulse width, making it simple to control from any microcontroller including Arduino, ESP32, Raspberry Pi, and STM32 using a single PWM-capable digital pin. With a torque of 1.8 kg·cm at 4.8V and a fast 0.1 second per 60° response speed, it offers dependable, repeatable movement for lightweight mechanical actuation tasks.

This micro servo is the go-to component for RC airplane control surfaces, small robotic arms, pan-tilt camera mounts, line-following robots, animatronics, IoT-controlled mechanisms, and any DIY project needing compact, low-cost rotational actuation. It ships with a set of mounting horns and screws, making installation straightforward right out of the box.
