28BYJ-48 5V Geared Stepper Motor with ULN2003 Driver Board Kit – For Arduino & Robotics

High Torque, Precise Movement

This isn’t just a motor; it’s a precision instrument. The 28BYJ-48 features an internal 1:64 gear reduction box. This gearing slows down the rotation to provide significantly higher torque (pull-in torque: 300 gf.cm), making it strong enough to move camera sliders, small robotic arms, or air conditioner vents.

Easy Driver Interface

Driving a stepper motor usually requires complex wiring, but this kit simplifies it. The included ULN2003 Driver Module features a socket that fits the motor’s plug perfectly. It uses a high-current Darlington Transistor Array to amplify your microcontroller’s weak signals to power the motor. Plus, it has 4 onboard LEDs (A, B, C, D) that light up to show you exactly which coil is active, making troubleshooting your code a breeze.

Versatile & Reliable

This is a 4-Phase 5-Wire unipolar stepper motor. It is widely supported by the standard Arduino Stepper.h or AccelStepper libraries, making it one of the most beginner-friendly motors for learning robotics.

Key Features

• Geared Design: 64:1 reduction ratio for high torque and fine positioning.

• Plug-and-Play: Motor connector snaps directly into the driver board.

• Visual Feedback: 4 LEDs on the driver board indicate stepper phase activity.

• Microcontroller Ready: Works seamlessly with 5V logic (Arduino, PIC, AVR).

• Compact Size: Small footprint fits easily into 3D printed housings.
