Parallax Continuous Rotation Servo Overview:
The Parallax Continuous Rotation Servo is an ideal hobby servo for robotics and basic movement projects. It is designed for continuous rotation and to be easily interfaced with any Parallax microcontroller. This is the servo on the BASIC Stamp Boe-Bot, Arduino-based Shield-Bot, SumoBot WX, and cyber:bot robot with micro:bit and is offered here as a replacement part. See the Parallax Tutorials site for use in Parallax robotics kits.
Key Features:
- Bidirectional continuous rotation
- 0 to 50 RPM, with linear response to PWM for easy ramping
- Accepts four mounting screws
- Easy to interface with any Parallax microcontroller, Arduino Uno, or other PWM-capable device
- Weighs only 1.5 oz (42.5 g)
Note: Servo current draw can spike while under load. Be sure that your application’s power supply and voltage regulator is prepared to supply adequate current for all servos used. Do not try to power this servo directly from a BASIC Stamp module’s Vdd or Vin pins; do not connect the servo’s Vss line directly to the BASIC Stamp module’s Vss pin.
Parallax Continuous Rotation Servo Details:

NOTE: Specifications subject to change slightly without notice. Product internal controls changed from analog to digital June 2022; but are a drop-in replacement for the previous version in Parallax robotics kits listed above. We recommend using two of the same type (two original or two digital) for the same robot.
