28BYJ-48 Stepper Motor & ULN2003 Driver Kit

The 64:1 reduction ratio means the motor shaft rotates 64 times for every one rotation of the output shaft. This gearing significantly increases the available torque at the output, allowing the compact 28BYJ-48 motor to move heavier loads or provide finer, more controlled movements than a direct-drive motor of similar size, making it ideal for precision.

Yes, the 28BYJ-48 stepper motor and ULN2003 driver kit are highly compatible with Arduino boards. The ULN2003 driver directly accepts 5V logic signals from Arduino's digital pins, simplifying the wiring and control. You only need to connect four output pins from Arduino to the driver's input for full directional and stepping control.

This 28BYJ-48 stepper motor and ULN2003 driver require a 5V DC power supply. While the driver can handle slightly higher voltages, the motor itself is rated for 5V DC. It's crucial to provide a stable power source capable of supplying at least 500mA to ensure optimal performance and prevent potential damage to the components during operation.

The motor's effective step angle is 5.625°/64, which is approximately 0.08789 degrees per step. This very small step angle, a result of the internal gearing, allows for extremely fine and precise rotational movements. It's crucial for applications like camera gimbals or small plotters where accurate positioning and smooth motion are paramount for optimal results.
