ULN2003 Stepper Motor Driver Board Test Module For Arduino AVR SMD

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.

Features:

1. Using ULN2003 high-power Darlington chip-driven stepper motor

2. Increased output expansion interface.

3.A, B, C, D light-emitting diode instructions four-phase stepper motor work with the state

of the standard stepper motor interface, can be used directly plug.
