Specification:

Features:

🔁 360° Endless Rotation

• Provides full circular motion in either direction, controlled by a standard PWM signal.

• Rotation does not stop at fixed angles—ideal for wheels, drive systems, and motion-based projects.

🧠 Simple Direction & Speed Control

• Controlled by pulse width:

  • ~1.5 ms = Stop

  • <1.5 ms = Rotate in one direction

  • 1.5 ms = Rotate in the opposite direction

• The further from 1.5 ms, the faster the rotation in that direction.

⚙️ Durable Plastic Gears

• Internal gear train made of lightweight nylon, offering reliable performance under light mechanical loads.

🔌 Easy to Interface

• Standard 3-wire servo connector (GND, VCC, Signal) works out-of-the-box with:

  • Arduino

  • Raspberry Pi

  • ESP32/ESP8266

  • STM32, ATmega, PIC, and more

🔋 Low Power Operation

• Runs on 4.8V to 6V, making it perfect for battery-powered mobile robots and DIY kits.

🔇 Low Noise & Lightweight

• Operates quietly and efficiently, weighing only ~9g, ideal for drones, rovers, or interactive prototypes.

🚗 Common Applications:

• Mobile Robots and rover platforms (wheel drives)

• Line-following robots

• DIY conveyor belts or motorized camera sliders

• Mini turntables for displays

• Educational robotic car kits

• Smart farming or delivery bots

Description:

The SG90 360° Continuous Rotation Servo Motor is a compact, affordable, and lightweight motor designed for projects that require full circular motion rather than angular positioning. Unlike standard servo motors that rotate within a 0–180° range, this version of the SG90 has been modified to allow endless rotation in either direction, making it ideal for use in mobile robots, conveyor belts, wheels, and simple drive mechanisms.

With a standard PWM control signal, you can adjust the rotation speed and direction (clockwise or counterclockwise) depending on the pulse width — making it incredibly easy to control with Pi, or other microcontroller platforms.

This micro servo is based on the trusted SG90 design, retaining its durable plastic gear mechanism, 3-pin connector, and low-power requirements, but with internal modifications for continuous movement rather than precise angular control.
