Stepper Motor 28BYJ 48 5V DC
The 28BYJ-48 is a small and affordable 5V DC stepper motor, perfect for use with Arduino, Raspberry Pi, and robotics projects. It is designed for accurate and smooth movement, thanks to its unipolar 4-phase structure and built-in 64:1 gear reduction system, which provides high torque at low speeds. With around 4096 steps per full rotation, it offers fine control for tasks like automated systems, pan-tilt cameras, smart gadgets, and DIY electronics. Commonly used in home automation and embedded systems, the 28BYJ-48 combines good performance with compact size and low cost. It is often used with the ULN2003 driver board for easy and reliable control.
