Hello, I am going to need to control about 50 mini stepper motors (4 wire bipolar) and need some advice. These are the small steppers inside a CD drive (see attachment) so they don't require much current. I don't need to control them at the same time so I was thinking I could use several multiplexer…

Hi, How many steps/second do you need? Can shift registers keep up??
