28BYJ-48 5V 4-Phase Stepper Motor with 1:64 Reduction

The 28BYJ-48 is a compact 5V 4-phase geared stepper motor engineered for smooth, low-noise movement. Designed to work seamlessly with a ULN2003 driver, it is compatible with 51, AVR, and ARM microcontroller platforms. This reliable motor is an ideal choice for robotics designers, students, and makers building precise motion-control projects.

Geared precision and stability

Featuring internal gear reduction with a 1:64 ratio and a step angle of 5.625 x 1/64, this motor delivers stable operation and low operating noise.

Driver and wiring flexibility

The 5-wire 4-phase stepper motor is typically driven using a ULN2003 controller chip. It can also be connected and operated in a 2-phase configuration.

Compact footprint

With a body diameter of 27 mm and dimensions of 31 x 27 x 19 mm, it fits neatly into constrained robotics assemblies while weighing just 35 g.

Package contents

This item includes 1 x stepper motor.
