Ok, heres HOWTO control stepper motor with pololu dual MC33887.


I used 23KM-K033-03 Stepper motor.

Here is simple code

/*

  MOTOR 23KM-K033-03
  
  WHITE AND YELLOW TOGETHER, NO CONNECT ELSEWHERE
  
  POLOLU 2x MC33887 CARD:
  BLUE MOTOR 1-1
  RED MOTOR 1-2
  BLACK MOTOR 2-1
  GREEN MOTOR 2-2
  
  ARDUINO FROM POLOLU 2 x MC33887
  PIN 8 = IN MOTOR 1-1
  PIN 9 = IN MOTOR 1-2
  PIN 10 = IN MOTOR 2-1
  PIN 11 = IN MOTOR 2-2

  */

#include <Stepper.h>
#define STEPS 200

Stepper stepper(STEPS, 8, 9, 10, 11);

void setup()
{
  stepper.setSpeed(100);
}

void loop()
{

  stepper.step(200);
}

So, with dual MC33887 you can control stepper motor very nice =)

EDIT: Here is a VIDEO (YOUTUBE)

You need to connect D2's and EN's to +05v...
