ULN 2003 Driver Module (Green)

Typically used with 28BYJ-48 stepper motor.

ULN2003 is a high voltage and high current Darlington transistor array products with high current gain, high operating voltage, wide temperature range, with a strong load capacity and other characteristics, adapted to the requirements of various types of high-speed high-power drive system. ULN2003A circuit is the United States Texas Instruments and Sprague company developed high-voltage high-current Darlington transistor array circuit, the paper describes its circuit structure, characteristic parameters and typical applications.

• Rated Voltage: DC5V 4-phase.
• LED Indicators: A, B, C, D four-phase LED shows the working status of the stepper motor.
• Easiness of Use: A, B, C, D light-emitting diodes deliver clear instructions for four-phase stepper motor usage with standard motor interface for direct plugging.
• Expandable Interface: The motor driver boasts a standard interface for plug-and-play ease and enhanced output expansion interface.
• High Power Chip: The ULN2003 driver board leverages a high power chip for efficient stepper motor driving.
