The 28YBJ-48 Mini Stepper Motor is a compact, low-cost 5V geared stepper motor designed for precise and controlled rotational movement in electronics, robotics, automation, and DIY projects.
With its integrated gear reduction mechanism, the motor provides higher output torque and slower rotational speed compared with a conventional small stepper motor. It is commonly used with driver boards such as the ULN2003 Stepper Motor Driver Module, making it easy to interface with Arduino, ESP32, Raspberry Pi, STM32 and other microcontroller platforms.
The 28YBJ-48 is an excellent choice for applications requiring controlled angular movement, positioning, rotation, and low-speed mechanical motion in a compact form factor.

How It Works
A stepper motor rotates by energizing its internal coils in a specific sequence. Each electrical step moves the motor through a small angular increment. By controlling the sequence and timing of the electrical pulses, a microcontroller can control the motor's direction and rotational movement.
The integrated gearbox reduces the motor's rotational speed while increasing the available output torque, making the 28YBJ-48 suitable for applications that require controlled, slower mechanical movement.
For microcontroller projects, the motor can typically be paired with a ULN2003 driver module, which provides the required transistor switching between the controller and motor coils.

- Arduino UNO / Nano / Mega
