The 28BYJ-48 is one of the most popular stepper motors for Arduino and DIY electronics projects — and this complete package pairs the motor with its matching ULN2003 driver board. Connect the driver to any Arduino board (UNO, Nano, ESP32) — see our Arduino Boards collection — and you have precise, high-torque motion control running in minutes, with no extra driver circuitry to build.

Unlike ordinary DC motors, a stepper motor moves in exact steps, so your project always knows its position — perfect for robotic arms, camera pan-tilt mechanisms, rotary platforms and any automation that needs repeatable precision.

Key Features

Frequently Asked Questions

Q: Does this package include the driver board?
A: Yes — you get both the 28BYJ-48 stepper motor and the ULN2003 driver board in one package, ready to connect.

Q: Can I control the 28BYJ-48 with an Arduino?
A: Absolutely. Connect the driver’s IN1–IN4 pins to four Arduino digital pins and power the board with 5V. Standard Arduino stepper libraries support it out of the box.

Q: What does the 64:1 gear ratio mean?
A: The internal gearbox multiplies torque 64 times while slowing the output shaft — giving strong, slow, ultra-precise movement (4096 tiny steps per full revolution).

Q: What voltage does the 28BYJ-48 need?
A: 5V DC. For light loads you can power it from the Arduino’s 5V pin; for heavier loads use a separate 5V supply. Browse our Motor Drivers for more options.

Q: How is it different from a normal DC motor?
A: A DC motor just spins; a stepper motor moves in exact, countable steps — so your Arduino always knows the shaft position without extra sensors.

Q: Where can I buy stepper motors in Pakistan?
A: Right here — QKZee Technologies stocks the 28BYJ-48 and other Motors at our Hall Road, Lahore shop with Cash on Delivery across Pakistan.
