ULN2003 12V Stepper Motor Driver

This 12V DC 28BYJ-48 Stepper Motor is a low-cost, high-quality geared stepper motor. Because of the system's stability and reliability, the 28BYJ-48 Stepper Motor and ULN2003 Stepper Motor Driver is a popular combination of stepper motor and stepper driver. 

The pack includes the ULN2003 Stepper Motor Driver, which is a Mini Stepper Motor Driver. The main function of the ULN2003 is to amplify the control signals from the Arduino so that they can be used to drive the 28BYJ-48 Stepper Motor.

If you want to control the stepper motor with the stepper motor driver, for that you will need a few essential components like


  • Stepper motor with a standard interface, when used directly pluggable.
  • A, B, C, D four-phase LED indicator which indicates the status of the stepper motor work.
  • Compact-size stepper motor perfect for small robotics applications.

Package Includes:

1 x 28BYJ-48 12V Valve DC Gear Stepper Motor

1 x ULN2003 Stepper Motor Driver

1. How does 28BYJ-48 stepper motor work?

  • The 28BYJ-48 stepper motor has four phases in total. The red wire is always pulled HIGH. The phase is energised when another lead is pulled LOW. The stepper motor only rotates when the phases are energised in a logical sequence known as a step sequence.

2. What is ULN2003 motor driver?

  • The ULN2003 is a popular motor driver IC that consists of an array of seven Darlington transistor pairs, each of which can drive loads of up to 500mA and 50V. On this board, four of the seven pairs are used.

3. What is the purpose of ULN2003?

  • The ULN2003 IC is a popular motor driver IC that is used when we need to drive high current loads with digital logic circuits such as Op-maps, Timers, Gates, Arduino, PIC, ARM, and so on.
