Hello!
I just recently bought 3x http://www.sparkfun.com/products/10846 from sparkfun, and I read the http://dlnmh9ip6v2uc.cloudfront.net/dat … GHM809.PDF and understood that I need 2 circuits each of them being able to switch polarity. Like an H-bridge. Sadly the only H-bridge that sparkfun sells can only give maximum of 1 amp while that stepper draws 1.7 amps / phase. I don’t really want to buy a stepper driver because then I will get a PCB and tons of other things I don’t really need.
So does anyone have any information regarding how I shall allow my arduino(nano) to control 3x stepper motors? (bipolar)
Extra: I’m fully aware of that I need an external power source, which I do have. I did also buy 10x N-mosfets. Thought I only needed 1 mosfet, now I kind of realize that in an H-bridge there are 4 total. so 8x for dual channel. So my calculations are quite wrong. But I’m sadly not 100% sure regarding the schematic because I keep “short-wire-ing” when I connect the wires in Fritzing.
