Description: Stepper motor can converts pulse signals into angular displacement or linear displacement. It is the main executive element in modern digital program control systems. The ULN2003 module is often used to drive a small five-wire four-phase motor, and there's A,B,C,D light diodes indicate the working state of the four-phase stepper motor. Equipped with a standard interface of the stepper motor,can directly plugged in and out. 5 line 4 phase can be used for ordinary ULN2003 chip driver, connect to the 2 phase , support the development board,With convenient use, direct docking. Widely application: It is suitable for various platforms such as 51?avr?arm Compatible with Arduino and the needs of robot design and development. Main Parameters: 1. Rated voltage: DC 5V 2.
