Specifications

Why Choose This ULN2003 Stepper Motor Driver Module?

• Plug-and-play motor connection: The onboard 5-pin female header accepts 28BYJ-48 stepper motors directly - no soldering or adapter wiring needed.
• Visual phase feedback: Four bright LEDs indicate which coil phases are currently energized, making debugging and learning stepper sequences intuitive.
• Built-in back-EMF protection: The ULN2003A IC includes integrated flyback suppression diodes, protecting your microcontroller from voltage spikes when motor coils switch off.
• High current handling: Each Darlington channel sinks up to 500 mA, comfortably driving small to medium unipolar stepper motors without external transistors.
• Universal logic compatibility: Works reliably with both 3.3V (ESP32, Raspberry Pi) and 5V (Arduino Uno, Mega) logic levels for maximum versatility.
• Compact and mountable: The small 35 x 32 mm form factor with M3 mounting holes fits neatly into enclosures, robot chassis, and breadboard-adjacent layouts.
• Supports multiple drive modes: Implement full-step, half-step, or wave drive sequences in software for different torque, speed, and resolution requirements.
• 100% authentic components: Sourced directly from trusted, authorized suppliers - no clones or counterfeit ICs.
• Fast shipping from Bengaluru: 1-5 day shipping, 7-8 day delivery across most of India; same-day dispatch available within Bengaluru.
• Expert technical support included: Get help with wiring, code, and troubleshooting via email and WhatsApp around the clock.

Project Ideas

• Automated Blinds & Curtain Controller: Use the ULN2003 module with a 28BYJ-48 stepper motor to build a smart curtain system that opens and closes on a schedule or via a smartphone app using ESP32 and Blynk.
• Mini CNC Plotter / Drawing Machine: Pair two stepper motors with ULN2003 drivers and an Arduino to create a compact pen plotter that converts digital designs into physical drawings on paper.
• 3D Printer Filament Winder: Build a motorized spool winder that evenly winds filament or wire using precise stepper control, adjustable speed, and an LCD display for monitoring.
• Robotic Arm Base Rotation: Add a stepper-driven rotational axis to a robotic arm project for smooth, repeatable angular positioning in pick-and-place applications.
• Camera Pan/Tilt Time-Lapse Rig: Create a motorized camera mount that slowly pans or tilts during time-lapse photography, delivering cinematic motion with sub-degree precision.
