I am a bit noob with all kind of stuff. I have seen that the ROB-09238 is 'famous' and I want to manage it with the RPi2.
Technically do I really need that, two L9110H can make the work?
and what about this http://www.hobbytronics.co.uk/motor-control/motor-drivers/h-bridge-driver-sn754410 is cheaper, can be used?
And in case do I need a driver any cheap that works with this stepper?
