5V 4-Phase Stepper Step Motor + ULN2003 Driver

The 5V 4-Phase Stepper Step Motor kit pairs a 28BYJ-48 geared stepper motor with a ULN2003 driver board. The motor moves in small, exact steps, and its built-in gearbox gives about 2048 full steps per output shaft turn, so you can set a position precisely without a feedback sensor. The driver board plugs straight into the motor and lets an Arduino, ESP32 or Raspberry Pi control it with four digital pins.

5V 4-Phase Stepper Step Motor Specifications

• Motor: 28BYJ-48, unipolar, 4-phase, 5 wires
• Rated voltage: 5 V DC
• Step angle: 5.625° per half-step at the motor, before the gearbox
• Gear reduction: about 1:64
• Steps per output turn: about 2048 full steps (4096 half-steps)
• Driver: ULN2003 Darlington array board with inputs IN1–IN4
• Indicators: 4 LEDs on the driver board show the active phases
• Connection: 5-pin plug from the motor to the driver board

5V 4-Phase Stepper Step Motor Applications

• Learning stepper motor control with Arduino and ESP32
• Rotating platforms, camera sliders and pointers
• Automatic blinds, feeders and valves
• Clock, gauge and display mechanisms
• Robotics and STEM projects

What's in the Box

• 1 × 5 V 4-phase stepper motor (28BYJ-48)
• 1 × ULN2003 driver board

Tip: Power the driver board from a separate 5 V supply rather than the Arduino 5 V pin, and connect the grounds together. The motor is slow (roughly 10–15 RPM), so use a moderate speed setting in the Stepper or AccelStepper library to avoid missed steps.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
