Description
The Servo Angle Expander is a specialized electronic signal converter designed to extend a standard servo’s operational rotation range up to a full 180 degrees. While typical RC receivers and controllers restrict servo travel to a 90-degree arc, this compact device processes and expands the PWM pulse width range to 500–2500us, unlocking the full mechanical potential of your servos for wide-angle steering, camera panning, or robotic articulation.
Constructed from high-quality electronic components, this module is exceptionally lightweight (weighing just 6 grams) and features a compact 134mm inline form factor that integrates seamlessly into existing wiring harnesses. Operating across a flexible 3.6V to 16V input voltage range, it is fully compatible with a wide variety of receivers and battery setups. Whether you are upgrading your RC car’s steering radius, expanding a boat’s rudder throw, or building complex robotic limbs, this expander provides a simple, plug-and-play solution.

Key Features
- Extended Angular Range: Expands standard control signals to a 500–2500µs PWM pulse width, allowing servos to achieve a full 180-degree rotation.
- Wide Input Voltage Range: Supports 3.6V to 16V DC supply voltages, ensuring compatibility with 1S to 3S LiPo setups and standard receiver power outputs.
- Ultra-Lightweight & Compact: Weighing next to nothing with a slim inline design, it adds virtually zero dead weight to your aircraft, vehicle, or robot.
- Durable Electronic Build: Fabricated using high-grade components for long-term operational stability and reliable signal conversion.
- Plug-and-Play Simplicity: Easily connects inline between your receiver and servo without requiring complex programming or external software.
Benefits
- Unlocks Servo Potential: Maximizes the mechanical travel of your existing servos, eliminating the restriction of standard 90-degree limits.
- Versatile Application: Ideal for custom builds where increased throw or wider mechanical sweep is mandatory for proper operation.
- Easy Installation: Inline layout allows for quick retrofitting into tight fuselages, vehicle chassis, or robotic enclosures.
- Broad Compatibility: Works seamlessly with a wide range of standard analog and digital RC servos across multiple hobby platforms.
Applications
- RC Cars & Trucks: Perfect for expanding steering throw angles for sharper turning radiuses in custom chassis builds.
- RC Boats & Ships: Excellent for increasing rudder deflection for tighter maneuvering control on the water.
- Robotics & Animatronics: Great for driving wide-angle joints, grippers, and movable head mechanisms in robotic projects.
- Pan-Tilt Camera Mounts: Enables wider panoramic sweep ranges for FPV cameras and sensor tracking platforms.
