28BYJ-48 Stepper Motor 5V DC

Overview

The 28BYJ-48 is a 5V unipolar stepper motor that comes with an internal gear reduction system. While it moves slower than a standard motor, the 1:64 gear ratio gives it enough power to lift small weights or turn heavy mechanisms with ease. It is a 4-phase motor, making it extremely easy to control using the standard Arduino Stepper.h library or the popular ULN2003 driver board.

Key Features

• Geared Precision: 1:64 reduction ratio provides high holding torque and precise positioning.

• 5V Operation: Designed to run directly from your Arduino or Raspberry Pi’s 5V power rail (using a driver).

• 4-Phase / 5-Wire: Simple wiring and wide library support for beginners.

• Quiet & Stable: Smooth operation with minimal vibration compared to larger NEMA motors.

• Standard Connection: Features a 5-pin XH-2.54 connector for plug-and-play use with ULN2003 driver boards.
