28BYJ-48 5V DC Steppper Motor with ULN2003 Driver Board
This small stepper is a great way to get things moving, especially when positioning and repeatability is a concern. The stepper motor has five color-coded wires allow it to be controlled by both unipolar and bipolar stepper motor drivers. All five wires are used when connect to a unipolar stepper motor driver. When used with a bipolar stepper motor driver, the center-tap red wires can be left disconnected.
