Max Output Sinking Current	500 mA per channel (Peak current capacity up to 600 mA)
Max Output Standing Voltage	50V DC Peak
Compatible Motor Styles	4-Phase, 5-Wire Unipolar Stepper Motors (e.g., 28BYJ-48)

Module Dimensions (approx.)	35 mm × 32 mm × 10 mm

The ULN2003 Stepper Motor Driver Board Module is a compact, high-current electronic switching breakout card designed to control inductive loads from low-power microcontrollers. Populated with a central ULN2003 Darlington transistor array chip, it bridges the current gap between logic boards (like Arduino or ESP32) and actuators. It acts as a set of digital switches, enabling low-current microchip pins to handle heavier current paths safely.

Integrated Darlington Transistor Array: Utilizes high-gain NPN Darlington transistor configurations to cleanly amplify low-power logic inputs.
Built-in Flyback Diodes: Features integrated suppression clamp diodes on each output channel to absorb and dissipate dangerous inductive voltage spikes from motor coils.
Real-Time LED Status Monitoring: Outfitted with 4 independent, on-board LEDs that give immediate visual feedback of active driver phases.
Direct Pluggable Keyed Socket: Includes a standard 5-pin XH-2.54 interface, allowing a 28BYJ-48 stepper motor to plug straight in without loose terminal wires.
