ULN2003 Driver Board Stepper Motor Blue

This ready-to-use module lets you drive popular unipolar stepper motors, such as the 28BYJ-48, directly from your microcontroller without the need for discrete transistors or extra wiring.

The board is populated with a ULN2003A Darlington transistor array, providing four high-current channels that safely switch loads up to 500 mA per coil. Clear silkscreen labels (IN1 – IN4, GND, VCC) and bright on-board status LEDs make setup and debugging fast and intuitive.

• Operating voltage: 5 V – 12 V DC
• Four driver outputs with integrated fly-back diodes
• Standard 5-pin JST-XH motor connector
• 7-pin male header for direct connection to Arduino, Raspberry Pi, ESP-based boards, and more
• Individual channel indicator LEDs show coil activity in real time
• Compact single-sided PCB with pre-soldered through-hole components
• Mounting holes for easy panel or chassis installation

Ideal for DIY CNC stages, camera sliders, robotics joints, 3D-printed mechanisms, and any project that needs precise, low-cost stepper control.
