28BYJ-48 Stepper Motor 5V with ULN2003 Driver Module

The 28BYJ-48 is a small, cheap, 5V geared stepping motors.

These stepping motors are apparently widely used to control things like automated blinds, A/C units and are mass produced.

Due to the gear reduction ratio of 64:1 it offers decent torque for its size at speeds of about 15 rotations per minute (RPM).

With some software “trickery” to accelerate gradually and a higher voltage power source (I tested them with 12 volts DC).

These little steppers can be purchased together with a small breakout board for the Arduino compatible ULN2003 stepper motor driver.
