Overview

Do you need little continuous rotation servos for a little project? Try this compact, lightweight servo that requires only 3V to operate.

It is an ideal servo motor for micro:bit GO bundle projects paired with our I/O adapter to bring both micro:bit control signals and direct battery current right to a breadboard. A 3-pin single-row header, available separately, will come in handy for connecting this servo to a breadboard.

Control this servo with PWM (pulse width modulation) signals.  Pulses in the 700-1500 µs range turn it clockwise; pulses in the 1500-2300 µs range turn it counterclockwise, 1500 µs will make it stop.  Need wheels? The Wheel/Tire for 3V Micro CR Servo (FT90R) presses right on to this servo's spline, just secure it with the included screw. Pick up a pair for your home made tiny robot project!

Features:

  • Operates at just 3V, ideal for two 1.5V batteries
  • Easy to control with simple PWM (pulse-width modulation) signals
  • Rotates continuously clockwise & counterclockwise
  • Set of servo horns is included
  • Accepts the Wheel/Tire for FT90R Mini CR Servo

Applications:

  • Animating mechanical props
  • Tiny home-made robots

Note: if you are looking for a tiny standard servo to turn to and hold a position, try the 3V Digital Micro Servo, Standard (FT90B).
