The MG90S is a metal gear micro servo motor with 180° rotation, PWM control, and dual ball bearings. Weighing just 13.6g, it delivers up to 2.2 kg·cm torque at 6V — ideal for RC models, robotics, and Arduino projects.

 

The MG90S is a compact metal gear micro servo motor designed for projects that demand precise angular control in a lightweight package. Unlike plastic-gear servos, the MG90S features metal gears and dual ball bearings, delivering improved durability and smoother motion under load. Operating on standard PWM (Pulse Width Modulation) at 50 Hz, it connects directly to any PWM-capable microcontroller pin — including Arduino UNO, Mega, Nano, and ESP32 — making it one of the most versatile micro servos available for makers and engineers.

Key Features

  • Metal Gear Construction: Copper metal gears resist wear far better than plastic alternatives → longer lifespan in high-cycle applications like robotic joints
  • Dual Ball Bearings: Reduce friction and play in the output shaft → more precise and repeatable positioning
  • 180° Rotation Range: Analog PWM servo with 1 ms–2 ms pulse width control → full 0° to 180° sweep for steering, tilting, and gripping mechanisms
  • High Torque for its Size: Up to 2.2 kg·cm at 6.0V → capable of driving small arms, rudders, and camera gimbals
  • Fast Response: 0.10 sec/60° at 4.8V → responsive enough for RC aircraft and agile robotic platforms
  • Standard PWM Interface: 50 Hz, 1–2 ms pulse width → natively compatible with Arduino Servo library, no extra drivers needed
  • Wide Operating Voltage: 4.8V – 6.6V → works with both 5V microcontroller supplies and 2S LiPo RC setups

Pinout & Wiring

Wire ColorSymbolDescription
🟤 BrownGNDGround — connect to GND of power supply and microcontroller
🔴 RedVCCPower Supply — connect to 4.8V–6.6V (e.g., 5V Arduino pin or external supply)
🟠 OrangeDATA / PWMPWM Control Signal — connect to a PWM-capable digital pin (e.g., D9 on Arduino UNO)

Wiring note: Connect the brown wire → GND, red wire → 5V (or external 4.8V–6V supply), and orange wire → PWM pin (e.g., D9 on Arduino). For reliable operation, use an external power supply capable of at least 1A — powering the servo directly from the Arduino 5V pin may cause voltage drops and reset issues.

Compatibility

  • Arduino UNO / Nano / Mega: Direct connection via any PWM pin; use the built-in Servo.h library. Power the servo from an external 5V source for best results.
  • ESP32 / ESP8266: Compatible via PWM output at 3.3V logic (signal level sufficient for most MG90S units); use external 5V power supply for VCC.
  • Raspberry Pi: Compatible via GPIO PWM; power VCC externally.
  • RC Receivers: Plug-and-play with standard RC PWM receivers (50 Hz, 1–2 ms).

Typical Applications

  • Steering servos in RC cars, boats, and model aircraft
  • Pan/tilt camera gimbal mechanisms
  • Robotic arm joints and gripper actuators
  • Quadcopter and drone control surfaces
  • DIY robotic projects and STEM educational kits
  • Animatronic and puppet control mechanisms

Frequently Asked Questions

Q: What is the difference between MG90S and SG90?
A: Both are micro servos with identical form factors, but the MG90S uses metal gears and dual ball bearings instead of the SG90's plastic gears. This makes the MG90S significantly more durable under repeated load — recommended for any application where the servo experiences real mechanical stress.

Q: Can I power the MG90S directly from the Arduino 5V pin?
A: For testing light loads it is possible, but not recommended for regular use. The MG90S can draw peaks well above the Arduino's onboard regulator capacity. Use a separate 5V supply (at least 1A) and connect grounds together for reliable operation.

Package Contents: 1× MG90S Micro Servo Motor, servo horn set (multiple horn types), fixing screws, and rubber damping grommets with brass eyelets.

⚠️ Note: Always use an external power supply capable of at least 1A when driving the servo under load. Do not power VCC directly from a microcontroller's 3.3V or 5V pin in demanding applications.
