S3003 Servo Motor 180° 12kg by Kuongshun — standard analog servo with PWM control, 4.8–6V operation, and up to 11kg/cm stall torque. Ideal for robotics, RC vehicles, and Arduino-based projects.

 

The Kuongshun S3003 is a standard-size analog servo motor offering 180° rotation range and up to 11 kg/cm stall torque at 6V. Compatible with the widely used Futaba S3003 form factor, it operates via standard PWM pulse-width control at 50 Hz, making it plug-and-play with Arduino, ESP32, and most RC receivers. Whether you're building a robotic arm, a pan-tilt camera mount, or an RC model, the S3003 delivers reliable torque and precise positioning at an accessible price point.

Κύρια Χαρακτηριστικά / Key Features

  • High Torque: Up to 11 kg/cm at 6V and 9.4 kg/cm at 4.8V → sufficient for medium-load robotic joints and steering mechanisms
  • Standard PWM Control: 50 Hz analog signal (20 ms period) → compatible with virtually all microcontrollers and RC systems
  • Wide Voltage Range: 4.8–6V DC → works with both 5V Arduino boards and regulated 6V RC battery packs
  • Fast Response: 0.16 sec/60° at 6V and 0.20 sec/60° at 4.8V (no load) → smooth, responsive actuation
  • Tight Dead Band: 0.1 ms → precise positional accuracy with minimal jitter
  • Brushed DC Motor: Simple and cost-effective drive mechanism with direct-drive potentiometer feedback
  • Plastic Gears: Lightweight gear train suitable for light to medium-duty applications
  • Compact Form Factor: 40.7 × 19.7 × 42.9 mm → fits standard servo mounts and brackets

Pinout & Wiring

Wire ColorSignalDescription
BrownGNDGround — connect to system GND
RedVCCPower supply 4.8–6V DC
OrangePWM SignalControl pulse input (50 Hz, 1–2 ms pulse width)

Wiring note: Connect the signal wire to a PWM-capable pin on your Arduino (e.g., D9, D10). Use the Arduino Servo.h library and call myservo.write(90) for 90° center position. Power the servo from an external 5–6V supply for torque-demanding applications — do not power high-torque servos directly from the Arduino 5V pin.

Compatibility

  • Arduino UNO / Nano / Mega: Fully compatible via 5V PWM signal. Use the built-in Servo.h library.
  • ESP32 / ESP8266: Compatible with 3.3V signal logic — signal voltage is within the required 3.0–5V peak-to-peak square wave range.
  • Raspberry Pi: Compatible via GPIO PWM or dedicated servo driver (e.g., PCA9685).
  • RC Receivers: Plug-and-play with standard RC systems operating at 50 Hz.

Typical Applications

  • Robotic arms & grippers: The 11 kg/cm torque handles light payloads in 4–6 DOF robot arms
  • RC vehicles & boats: Standard steering servo for 1/10 to 1/8 scale RC models
  • Pan-tilt camera mounts: Smooth 180° sweep for surveillance or FPV gimbal systems
  • Arduino maker projects: Door openers, automated valves, animatronics, and school/university prototypes
  • Educational robotics: Perfect for students learning servo control and PWM principles

FAQ

Q: Can I power the S3003 directly from the Arduino 5V pin?
A: For light-load testing, yes — but for actual torque-demanding use, always power the servo from an external 5V or 6V supply. Drawing high current through the Arduino regulator can cause resets or damage the board.

Q: What is the difference between 4.8V and 6V operation?
A: At 6V, the servo delivers higher torque (11 kg/cm vs 9.4 kg/cm) and faster speed (0.16 s/60° vs 0.20 s/60°). Use 6V when torque is critical; use 4.8V for standard RC battery packs.

Package Contents: 1× S3003 Servo Motor with connector cable

⚠ Note: Do not exceed 6V supply voltage. Avoid stalling the servo for prolonged periods, as this may overheat the brushed motor and damage plastic gears. Operating temperature range: 0°C to +55°C.
