Description
28BYJ-48 Stepper Motor 5V with ULN2003 Driver Module
The Stepper Motor 5V with ULN2003 is a compact motion device combined with a matched driver module for easy and reliable integration in microcontroller and robotics projects. Typically based on the popular 28BYJ-48 unipolar stepper motor, this kit includes a dedicated ULN2003 Darlington transistor array driver board that amplifies control signals to safely drive the motor coils. Operating at 5 VDC, it delivers finely stepped motion with a geared reduction for increased torque and positional precision. This combination simplifies interfacing with Arduino, Raspberry Pi, ESP32, and similar development platforms, allowing for accurate control of rotation, speed, and direction in automation, robotics, and DIY applications.
Features
- Includes 5V unipolar stepper motor with geared output for enhanced torque.
- ULN2003 driver board with four Darlington transistor channels for coil driving.
- Four LED indicators on driver board show coil activation status.
- Standard 5-wire motor interface for plug-and-play connection.
- Easy microcontroller integration (Arduino, Raspberry Pi, ESP series).
- Compact and lightweight module suitable for prototyping and education.
