The GWSVO008B S35 STD continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. It can be controlled directly by a microcontroller without any additional electronics, which makes it a great actuator for beginner robotics projects.

The servo has an 11" (270 mm) lead that is terminated with a JR-style connector and comes with the following included hardware:

  • 1x small X-horn
  • 1x large X-horn
  • 1x large wheel
  • 1x 6-star horn
  • 1x double-arm horn
  • mounting hardware: 4x grommets, 4x eyelets, 4x screws
  • 1x horn mounting screw

This robotics servo is compatible with Pololu servo controllers and has a Futaba-compatible output shaft, which means it works with Pololu servo wheels and sprockets. For detailed specifications, please see the specs tab.
