This configurable metal-geared servo can be used as a standard angular servo, a custom-limit angular servo, or a continuous-rotation actuator. It accepts conventional PWM input, so it can drop into many robotics builds while adding useful reconfiguration options when used with the optional REV SRS Programmer.
Out of the box, it behaves as a 270° positional servo with a 500 µs to 2500 µs pulse range. With the optional programmer, you can set custom angular travel up to 280° or convert it for continuous rotation, helping avoid mechanical adapters or permanent modifications.
The servo uses durable metal gearing, a standard 25-tooth spline, and M3 tapped mounting options. A horn assortment and mounting hardware are included for easier integration into robotics mechanisms.
Features:
- Configurable as a standard angular, custom-limit angular, or continuous-rotation actuator.
- Programmable with the optional REV SRS Programmer.
- Accepts conventional PWM input.
- Set travel limits or unlock continuous spinning.
- Out-of-the-box 270° positional servo behaviour.
- Custom angular ranges up to 280° with the SRS Programmer.
- Durable metal gearing.
- Standard 25-tooth spline with M3 tapped mounting options.
- Includes a horn assortment and mounting hardware.

- Spline Internal Thread Depth: 6mm
- Size: 40.2mm x 20.0mm x 38.0mm
- Weight: 2.05 oz.
A practical choice for robotics mechanisms that need positional control, configurable travel, continuous rotation capability, and robust metal gearing.
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- Thread
- A low-power wireless mesh networking standard designed for smart home and IoT devices. It matters because Thread devices can relay messages through each other, helping build reliable networks for sensors and controllers.
- 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.
