SKU: VE-097 Category: Motors

The 28BYJ-48 5V Unipolar Geared Stepper Motor is a miniature, low-cost, 4-phase electronic step actuator equipped with an internal 64:1 reduction gearhead. Instead of relying on raw direct rotation, this motor moves in highly predictable, fractional increments, allowing for exceptionally precise open-loop position control. Operating on low-voltage logic power, it is the classic entry-level component for automation training, miniature smart home air vents, security cameras, and budget-friendly Arduino robotics projects.

✨ Key Features

Integrated Step Reduction Gearbox: Features an internal 64:1 mechanical gear assembly that multiplies holding torque while ensuring stable, sub-RPM movements.
High Positional Step Resolution: Delivers a stride resolution of 5.625° per step natively, expanding to over 2,048 discrete steps per full 360° rotation when combined with the internal gear ratio.
Low-Voltage Microcontroller Support: Operates directly on standard 5V DC power rails, making it safe to power from basic development boards using a simple driver interface.
Plug-and-Play Driver Matching: Terminated with a standardized 5-wire connector keyed perfectly for immediate attachment to cheap ULN2003 transistor arrays.
