Product Description (Detailed):

Unlock precise motion control for your electronics projects with our popular 28BYJ-48 Stepper Motor coupled with the essential ULN2003 Driver Board. This widely used combination is a favorite among hobbyists, students, and engineers for its affordability, ease of use, and reliability in applications requiring accurate angular positioning. Operating on a common 5V DC supply, this unipolar geared stepper motor provides excellent torque for its size, making it ideal for a multitude of tasks from robotics and automation to camera sliders and precise valve control.

The 28BYJ-48 stepper motor features a built-in reduction gearbox, delivering a higher effective step resolution (typically 5.625 degrees per step, translating to 4096 steps per full 360-degree revolution, or about 0.08789 degrees per microstep when driven in full-step mode and considering the gear ratio). This allows for very fine and repeatable movements. The included ULN2003 Driver Board simplifies interfacing with microcontrollers like Arduino, Raspberry Pi, ESP32, and PIC. The ULN2003 is a Darlington array IC that efficiently handles the current requirements of the stepper motor coils, protecting your microcontroller's delicate I/O pins. Integrated LEDs on the driver board provide visual feedback of the coil activation sequence, aiding in troubleshooting and understanding motor operation. Whether you're building a DIY CNC machine, a smart home device, or an automated dispensing system, this 28BYJ-48 stepper motor kit with ULN2003 driver provides a robust, easy-to-implement solution for all your precise motion control needs.

The 28BYJ-48 Stepper Motor and ULN2003 Driver Module is a beginner-friendly and affordable solution for creating motion in DIY electronics, robotics, and CNC projects. The 28BYJ-48 is a 5V unipolar stepper motor featuring 4-phase 8-beat operation and geared output for precise step movement.

Paired with the ULN2003 driver board, it simplifies control using logic-level signals from microcontrollers. The board includes indicator LEDs to show active control lines, helping with troubleshooting during testing and development.

Ideal for low-power automation, camera sliders, Arduino projects, and electronic hobby kits.
