Overview

Do you need little standard servos for a little mechanical 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.  It accepts 500-2500 µs pulses, and a 1500 µs pulse will make it turn to and hold its neutral position in the center of its 180° range. 

Features:

  • Operates at just 3V, ideal for two 1.5V batteries
  • Easy to control with simple PWM (pulse-width modulation) signals
  • Rotates to and holds any position in a 180° range
  • Set of servo horns is included

Application ideas:

  • Animating a mechanical character
  • Raising or lowering a signal flag
  • Opening or closing an access hatch
