ULN2003 Stepper Motor Driver Board Module for 28BYJ-48
VAT inclusive; Computed calculations added locally.
Overview
The ULN2003 Stepper Motor Driver Board provides a simple interface between a microcontroller and a compatible 4-phase stepper motor. Based on the ULN2003A driver IC, the board amplifies low-power control signals so they can be used to drive the motor coils in sequence.
Designed for use with the popular 28BYJ-48 stepper motor, the module is useful for Arduino projects, robotics, automation, and electronics learning. Its straightforward interface makes it convenient for projects where a dedicated motor-driving stage is required.
Four onboard LEDs provide visual indication of the control signals, which can be helpful when testing code and troubleshooting motor-control sequences. The compact board is well suited to prototyping and educational applications.

Product Technical Information
Technical Details
The ULN2003 Stepper Motor Driver Board Module is a compact motor-control interface based on the ULN2003A Darlington transistor array. It is primarily intended for driving small 4-phase stepper motors, particularly the commonly used 28BYJ-48.
Key Features
- ULN2003A Darlington transistor array
- Designed for compatible 4-phase stepper motors
- Commonly paired with 28BYJ-48
- Stated DC supply range of 5V–12V
- Four onboard LED signal indicators
- Simple interface for Arduino and other microcontrollers
- Compact design for prototyping and DIY projects
- Useful for stepper motor control and automation experiments
How It Works
A microcontroller sends control signals to the input pins of the ULN2003A. The driver circuitry switches the corresponding motor coils according to the control sequence, allowing the connected stepper motor to rotate in controlled steps.
The onboard LEDs indicate the input/control activity, making it easier to observe the sequence during development and troubleshooting.
Applications
This driver board can be used for:
- Arduino stepper motor projects
- Robotics
- Mini CNC and positioning projects
- DIY automation
- Embedded motion-control systems
- Educational electronics experiments
- 28BYJ-48 motor projects
- Prototyping and mechanical control systems
Important Notes
- Confirm that the connected motor is compatible with the driver board before use.
- The provided specification lists a 5V rated voltage per phase, while the board supply is listed as 5V–12V. The appropriate supply should be selected according to the connected motor and its electrical requirements.
- Do not assume the stated step angle and reduction ratio apply to every motor connected to the board; these specifications are associated with the supplied source information and may correspond to a particular 28BYJ-48 configuration.
- A separate warranty period is not included here because the source-specific warranty terms have been removed.
Package Includes
- 1 × ULN2003 Stepper Motor Driver Board 5V–12V
