(2)Driver Board ULN2003 
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. ULN2003 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.

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.
