Hi 'yall
I need to power keling stepper http://www.kelinginc.net/KL23H51-24-8B.pdf
I had pololu 1203 driver that burnt up when I connected it bipolar-parallell (opps neded 3.4A).
I would like to use Mosfet controller instead now, so if any of you has a design with 1/2 - 1/8 microstepping that I could use, that would be great.
I looked at the LinoStepper but they recomend using only 3A. So something like that (but Arduino instead of PIC 
) with 5-10A range, so the controller could be used at 3.4A with ease....
One more thing.... If I can use the mosfets from SparkFun that would be a ++ 
since I have a few of them.
ps. I did order replacement Pololu boards, can I use 2 of them wired together to get more amps out? Like piggybackinng those H-bridges that are so popular
