28BYJ-48 5V DC Stepper Motor:

The 28BYJ-48 is a popular and widely used stepper motor in various hobbyist and DIY projects. Here's some information about this stepper motor:

1. Type: The 28BYJ-48 is a small stepper motor commonly used in low-cost applications, such as Arduino projects, robotics, 3D printers, camera sliders, and more.
2. Size: This stepper motor is relatively small, with dimensions of approximately 28mm in diameter and 48mm in length, hence the name 28BYJ-48.
3. Voltage: The 28BYJ-48 stepper motor typically operates at 5V DC. This voltage is compatible with many microcontroller platforms, including Arduino, Raspberry Pi, and others.
4. Step Angle: The 28BYJ-48 stepper motor has a step angle of 5.625 degrees. This means it requires 64 steps for a full 360-degree rotation.
5. Gear Reduction: One of the distinctive features of the 28BYJ-48 motor is its built-in gear reduction mechanism. This gearbox typically reduces the motor's speed and increases its torque output. The most common gear reduction ratio for this motor is 64:1, resulting in a higher torque output but slower speed.
6. Control: The 28BYJ-48 stepper motor can be controlled using a stepper motor driver board, such as the ULN2003 driver board, which is commonly used with this motor. The ULN2003 driver board allows you to interface the motor with microcontrollers like Arduino and control its rotation and direction using digital signals.
7. Applications: Due to its compact size and relatively low cost, the 28BYJ-48 stepper motor is suitable for a wide range of hobbyist and DIY projects. It's commonly used in applications where precise control over rotation is required, such as in robotic arms, CNC machines, automated camera systems, and more.
8. Limitations: While the 28BYJ-48 stepper motor is suitable for many hobbyist projects, it's essential to note that it may not be suitable for high-torque or high-speed applications. Additionally, its relatively low resolution (64 steps per revolution) may limit its precision in certain applications compared to higher-end stepper motors.
