connect three stepper motors to control them in the same rotation & speed

How to connect three stepper motors to control them in the same rotation speed and direction and in the same time, by using mini pro arduino? I could’ve used the regular size of arduino and shields but the space is limited this is why I am using min pro arduino.

Thanks,

If both speed and direction always is the same for all 3 You can tie together DIR, PULSE and probably ENABLE, saving I/O.
Search this Forum for stepper info. There are several intruductionary topics telling how to run steppers.
