High-Precision Motion for Your Next STEM Project
The 28BYJ-48 stepper motor is a cornerstone of DIY electronics. Unlike standard DC motors that spin freely, this stepper motor moves in precise increments, allowing you to control the exact position of your mechanical parts. With an internal 1:64 reduction gear ratio, it delivers impressive torque despite its compact size, making it capable of moving heavier loads with ease.
Plug-and-Play ULN2003 Driver Board
Connecting high-power motors directly to a microcontroller can be risky. The included ULN2003 Driver Board acts as the perfect intermediary. It features a high-current Darlington array to safely power the motor while receiving logic signals from your Arduino or Raspberry Pi. The board includes an XH-5P socket, allowing you to plug the motor directly in—no soldering or messy wiring required.
Real-Time Monitoring & Feedback
Visual troubleshooting is essential for learning. The driver board is equipped with four onboard LEDs (A, B, C, D) that light up to show the current phase of the motor. This provides immediate visual confirmation that your code is working correctly and allows you to understand the logic behind 4-phase motor stepping.

FAQ Section
FAQ Section
Q: Can I run this motor directly from an Arduino 5V pin?
A: While it is possible for testing, we recommend using an external 5V power source for the driver board to avoid putting excessive electrical noise or current load on your Arduino's internal regulator.
Q: Does this kit include the jumper wires for connection?
A: This kit includes the motor and the driver board. You will need standard female-to-male or female-to-female jumper wires to connect the driver board to your microcontroller.
Q: How many steps are in a full 360-degree rotation?
A: Due to the 1:64 reduction gear, it takes approximately 4096 steps (in half-step mode) for the output shaft to complete one full revolution.
