Unipolar Stepper Motor 28-BYJ48



The 28-BYJ48 unipolar stepper motor has five or six wires and four coils (actually two coils divided by center connections on each coil). The center connections of the coils are tied together and used as the power connection. They are called unipolar steppers because power always comes in on this one pole.
The 28-BYJ48 Even comes with Breakout using ULN2003 As a Motor driver chip
