Overview
The 28BYJ-48 Stepper Motor 5V DC is an affordable, compact unipolar stepper motor designed for precise motion control in robotics, automation, camera rigs and DIY electronics. With a native motor step angle of 5.625° (64 steps per revolution) and an integrated 1:64 gearbox, the 28BYJ-48 increases torque and delivers fine positional control from a single 5V DC supply.
Key Benefits
Precision and torque
- 64 steps per motor revolution (5.625° per step) before gearing.
- 1:64 gearbox multiplies torque and refines effective resolution for smoother movement and higher positional accuracy.
- Common effective output used in many projects: 4096 steps per output revolution for precise micro-positioning.
Easy integration and control
- Unipolar coil arrangement simplifies wiring and driving from microcontrollers.
- Works seamlessly with Arduino, Raspberry Pi, ESP modules and other development boards.
- Compatible with popular driver modules such as the ULN2003 breakout board for safe, reliable switching.
Low voltage operation
- Operates on 5V DC, ideal for battery-powered and portable applications.
- Gearbox provides more torque than a similar direct-drive motor, suitable for small load-bearing tasks.

Wiring and integration tips
- Always use a driver board (ULN2003 or compatible) to isolate the microcontroller from the motor coils and to handle coil current safely.
- Provide a stable 5V DC supply sized to handle motor and driver current; avoid powering the motor from MCU pins.
- Implement step sequencing or microstepping in software to reduce vibration and achieve smoother motion. Libraries such as AccelStepper for Arduino help manage speed and acceleration.
- If the load is heavier than expected, add mechanical gearing or choose a higher-torque motor.
- Decouple the motor supply with capacitors and keep wiring short to reduce electrical noise and interference.
Quick start guide (Arduino)
- Connect the 4-pin connector from the ULN2003 driver board to the 28BYJ-48 motor socket.
- Wire the driver VCC to a stable 5V supply and GND to ground. Connect the ULN2003 IN pins to Arduino digital outputs.
- Install a stepper control library (for example, AccelStepper) and configure the step sequence to match the motor wiring.
- Begin with low speed and acceleration values, then tune for smoother motion and reduced resonance.
Frequently asked questions
Can I drive the 28BYJ-48 directly from an Arduino pin?
No. The motor coils draw more current than MCU pins can safely supply. Always use a driver such as the ULN2003 or an equivalent transistor/driver module.
What is the effective step resolution with the gearbox?
The motor has 64 steps per revolution. With the 1:64 gearbox the commonly used effective step count is 4096 steps per output revolution. Verify your wiring and step mode to calculate exact increments for your control code.
Is this motor suitable for high-speed continuous rotation?
The 28BYJ-48 is optimized for low-to-moderate speed, high-precision tasks. For sustained high-speed operation, choose a motor rated for higher RPM and continuous duty.
Why choose the 28BYJ-48 Stepper Motor 5V DC?
The 28BYJ-48 offers an excellent balance of cost, size and performance for hobbyists, educators and entry-level automation projects. Its 5V operation, unipolar design and integrated gearbox make it ideal for Arduino and Raspberry Pi projects where compact size, low voltage and straightforward integration are priorities.
