ULN2003 Driver Board Stepper Motor Green

The ULN2003 Driver Board Stepper Motor module, on a green PCB, uses the ULN2003 Darlington transistor array to drive small unipolar stepper motors such as the 28BYJ-48 from a microcontroller. Four of its channels switch the four motor coils, so an Arduino, ESP32 or Raspberry Pi can turn the motor step by step with only a few wires.

ULN2003 Driver Board Stepper Motor Specifications

• Driver IC: ULN2003, 7-channel Darlington transistor array
• Output rating per channel: up to 500 mA, 50 V maximum (IC rating)
• Protection: built-in clamp diodes for inductive loads
• Inputs: TTL and CMOS compatible logic inputs
• Suited motors: 5-wire unipolar steppers such as the 28BYJ-48
• PCB colour: green

ULN2003 Driver Board Stepper Motor Applications

• Driving 28BYJ-48 steppers in small rotating mechanisms
• Camera sliders, turntables, smart blinds and valve controls
• Switching relays, solenoids or LEDs as a general low-side driver
• Robotics, school projects and STEM labs

What's in the Box

• 1 × ULN2003 stepper motor driver board, green (motor not included)

Tip: Power the motor from a separate 5 V supply rather than the Arduino 5 V pin when running more than one motor, and connect the grounds together. In the Arduino IDE, the built-in Stepper library or the AccelStepper library makes it easy to set speed and direction.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
