ULN2003AN ULN2003 Stepper Motor Driver Module Board for Arduino 28BYJ-48 5V 12V High Power Development System Board

ULN2003 high power chip drives stepper motor

A, B, C, D LEDs indicate the status of the four-phase stepper motor when it is running

Equipped with a standard interface for stepping motor, which can be directly inserted when using.

Wiring method:

The IN1~IN4,VCC,GND on the left correspond to the 4 IO lines of the microcontroller;

The white socket pins on the right side are defined as  A, B, C, D,VCC from top to bottom (connected to the stepper motor common line, A phase, B phase, C phase, D phase);

It can be used directly by plugging into the microcontroller development board or system board. It needs to lead out 4 IO ports, 5V and ground from the development board.

Development board/system board and motor driver board are connected by 6 dupont wires
