The MG90S Micro Servo Motor (360° Continuous Rotation) is a compact, hobby-friendly analog RC servomotor designed for robotics, RC models, and DIY automation projects that need controlled continuous spinning in a small footprint. This version is continuous rotation, meaning it behaves like a tiny geared motor driven by a standard servo PWM signal—ideal for robot wheels, rotating platforms, feeders, mini conveyors, and lightweight drive mechanisms.

How Continuous Rotation Works (Speed + Direction)

Unlike positional servos (that move to a fixed angle), a continuous rotation servo uses PWM to control rotation direction and speed:

  • Neutral / Stop: ~1.5 ms (1500 µs) pulse width
  • Below neutral: rotates one direction (speed increases farther from neutral)
  • Above neutral: rotates the other direction (speed increases farther from neutral)

This makes it very easy to control using common servo libraries on Arduino/ESP32 and RC receivers.

Wiring (Standard 3-Wire Servo)

Typical wiring colors:

  • Brown / Black → GND
  • Red → VCC (4.8V–6.0V DC)
  • Orange / Yellow → PWM Signal

Power Notes (Important for Stability)

Servos can draw higher current during startup, load changes, or stalls. For best results:

  • Use a separate regulated 5V supply when possible (especially for multiple servos)
  • Always connect grounds together (servo GND ↔ controller GND)
  • Avoid powering heavy servo loads directly from weak USB ports or small onboard regulators

Key Benefits

  • 360° continuous rotation for drive and rotation mechanisms
  • Micro size for compact robots and tight mechanical assemblies
  • Analog RC PWM control compatible with Arduino, ESP32, and standard RC systems
  • Plastic gear design keeps weight low for educational and DIY builds
  • Accessories included for easy mounting and quick assembly
