Stepper Motor With Driver 5V

The most accessible introduction to stepper motors: a 5 volt geared unipolar stepper supplied with its ULN2003 driver board, so the complete set costs less than most bare steppers. Its internal 64:1 gearbox gives fine positional resolution and enough torque for light mechanisms, and it runs straight from an Arduino's 5V rail with four digital pins. It is slow and not powerful, so it suits small valves, dials, camera sliders and learning — not machine axes. For those, use a NEMA 17 with a proper driver. Driver board included, complete set ready to use; Runs from an Arduino 5V supply, no external power needed; Fine positional resolution from the internal gearbox; The cheapest way to learn stepper control
