This is ULN2003 Stepper Motor Driver Board, small size and easy to use. It uses the ULN2003 driver chip to amplify the control signal from the Arduino. This Ultra Lightweight and cheap option commonly used to run and control the small applications stepper motors.

It uses the ULN2003 DARLINGTON ARRAYS to drive the 4-phase 5-wire stepper motor (5v-12v).It's easy to use Arduino or other development platform to drive the stepper motor by this diver board.

Specifications:

• 7 high-voltage and high current Darlington pairs
• 50V and 500mA for each pair
• Input pins triggering voltage: 5V
• All seven Output pins can be connected to gather to drive loads up to 3.5A
• Low cost and Reliable
