Description
The ULN2003 is one of the most common motor driver ICs, consisting of an array of 7 Darlington transistor pairs, each pair is capable of driving loads of up to 500mA and 50V.The board has a connector that mates the motor wires perfectly which makes it very easy to connect the motor to the board.
USES:
ULN2003 Stepper Motor Driver Board uses the ULN2003 DARLINGTON ARRAYS to drive the 4-phase 5-wire stepper motor (5v-12v). It's easy to use Arduino or another development platform to drive the stepper motor by this diver board.
A Stepper Motor Driver is the driver circuit that enables the stepper motor to function the way it does. For example, stepper motors require sufficient and controlled energy for phases in a precise sequence. Due to this, stepper motors are considered more advanced than the typical DC motor.

Stepper Motor Wiring
1. A 4-way input of I1, I2, I3, and I4 corresponds to the 4 IO lines of MCU.
2. The motor stepper directly plugs into the motor interface, pay attention to the socket groove joints corresponding to the convex side.
