A 9g micro servo with 300° rotation and a built-in clutch mechanism that protects the servo from damage when external forces are applied. If the servo angle is changed by an external force during operation, the clutch allows it to automatically reset and continue working without stripping gears or burning out.
An electronic protection feature automatically cuts power after 5 seconds of being stalled, preventing overheating and burnout. The extended 300° range provides more travel than standard servos. Compatible with Arduino servo libraries using PWM control.
Key Features
- Clutch Protection – Automatically resets when forced out of position by external loads
- Electronic Stall Protection – Shuts off power after 5 seconds of continuous stall
- 300° Rotation – Extended range within 500–2500μs pulse width
- Low Power – Runs from standard battery or USB power sources
- Arduino Compatible – Works directly with Arduino servo libraries
Specifications
- Operating Voltage – 4.8–6V DC
- Operating Angle – 300° ±10°
- Static Current – ≤8mA (at 6V)
- No-Load Current – ≤110mA (4.8V) / ≤120mA (6V)
- Stall Current – ≤700mA (4.8V) / ≤800mA (6V)

Jargon buster
Plain-language definitions for the technical terms used above.
- Clutch servo
- A servo with a built-in clutch that can slip or reset if the output arm is forced by hand or by a mechanism. This matters in robots and models because it can reduce damage when the servo is pushed past its commanded position.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- Stall torque
- The maximum twisting force a servo can produce when its output is held still and cannot move. It helps you judge whether the servo is strong enough for a robot joint, steering linkage, or other load.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
