Hi guys, ive been really bussy and leave this for a while. Ok, im listing all electronic parts i will need, let me know if i will need more electronic parts:

3 Nema 3.1nm motors.
Drivers (this will be enought for controll motors?)
Match3 Software

I'd like to learn how this exactly works, i means, each driver per motor, what exactly driver does? and how works breakout board? how they will be wiring? Also i would like to know if i can convert parallel to usb just with a cable like this or i really will need something like this, why not the first simple cable and why that board?

Any input will be appreciate it a lot.

Thanks.

Walter R.
