28BYJ-48 Stepper Motor DC 5V

28BYJ-48 5V Stepper Motor (Geared)

The 28BYJ-48 DC 5V Stepper Motor is a compact, economical, and reliable geared stepper motor widely used in robotics, automation, and DIY electronics projects. Known for its stable performance and ease of use, it is ideal for low-speed, high-precision applications.

This motor is a unipolar 5-wire stepper motor featuring a built-in 64:1 reduction gearbox, allowing it to deliver good torque at low speeds of approximately 15 RPM. It is commonly used with a ULN2003 stepper motor driver, which amplifies control signals from microcontrollers such as Arduino and other development boards.

For optimal smoothness and torque performance, it is recommended to operate the motor in half-step mode using an 8-step control sequence.

Key Features

The motor is brand new and built with reliable components for consistent operation. Its compact size makes it ideal for small robotic mechanisms and embedded systems. It features a standard interface for easy plug-and-play connectivity and operates using four-phase drive sequences (A, B, C, D). The geared design ensures stable and precise rotational control.
