SG90-360 Micro Servo Motor with 360° continuous rotation. Weighing just 9g, it is ideal for robotics, wheeled platforms, and any project requiring unlimited rotation. Fully compatible with Arduino and most microcontrollers.

 

The SG90-360 Micro Servo Motor (MPN: SG90-360) is the continuous rotation variant of the iconic SG90 servo — one of the most widely used servo motors in the maker and robotics community. Unlike standard 180° servo motors that move to a fixed angle and stop, the SG90-360 spins continuously in either direction, making it the go-to choice for wheels, conveyor mechanisms, and any application that demands unlimited rotational movement. At just 9 grams, it delivers an exceptional balance of compact size and usable torque for its class.

Key Features

  • Continuous 360° Rotation: Spins freely in both directions — unlike standard servos — enabling wheel drive and rotating mechanisms.
  • Ultra-Lightweight (9g): Minimises payload on frames and chassis → ideal for lightweight robots and drones.
  • Standard PWM Control: Controlled via standard servo PWM signal (same as any hobby servo) → plug-and-play with Arduino Servo library.
  • Compact Form Factor: Small footprint fits tight enclosures and mini robot platforms.
  • 3-Wire Interface: Signal, VCC, GND — straightforward wiring, no driver board required.

Pinout & Wiring

Wire ColourSymbolDescription
Orange / YellowSIGPWM control signal from microcontroller
RedVCCPower supply positive
Brown / BlackGround / power supply negative

Wiring note: Connect the SIG wire to any PWM-capable digital pin on your Arduino (e.g. D9). Power the servo from a 5V supply; avoid drawing servo power from the Arduino 5V pin under load — use a separate supply for best stability.

Compatibility

  • Arduino UNO / Nano / Mega: Native compatibility via the built-in Servo.h library. Use servo.write(90) to stop, values above/below 90 control direction and speed.
  • ESP32 / ESP8266: Compatible using the ESP32Servo library; operates at 3.3V logic levels — signal pin is safe to connect directly.
  • Raspberry Pi: Controllable via GPIO PWM; power servo independently from the Pi's 5V rail to avoid brown-outs.

Typical Applications

  • Wheeled robots: Drive the wheels of a two-wheel differential robot directly — the most common SG90-360 use case.
  • Mobile platforms: Power small autonomous vehicles or Arduino-based rover projects.
  • Conveyor belts: Drive a compact belt mechanism in maker projects and automation demos.
  • Camera pan mechanisms: Provide continuous panning motion for surveillance or tracking systems.
  • Educational robotics kits: A staple component in STEM kits and university electronics labs.

FAQ

Q: What is the difference between the SG90-360 and the standard SG90?
A: The standard SG90 rotates to a set angle (0–180°) and holds position. The SG90-360 removes the mechanical stop and feedback potentiometer, allowing continuous spinning in both directions — speed and direction are controlled by the PWM pulse width.

Q: How do I stop the SG90-360 from spinning?
A: Send a PWM pulse corresponding to the neutral point (typically servo.write(90) with the Arduino Servo library). The exact neutral value may vary slightly per unit and can be trimmed in code.

Package Contents: 1 × SG90-360 Micro Servo Motor (horn accessories may be included depending on batch).

⚠ Note: Do not power the servo directly from the Arduino 5V pin when under mechanical load. Use a separate regulated 5V supply to prevent microcontroller resets or damage.
