Re: Bi-Polar Motor Driver 4A per phase 48V (opinions)

Steve's L6203 design looks a good one, and I was originally going to
take that route, but gave in and bought Gecko 210's to save time and
for compatibility with future larger machines.

I'm not keen on his old parallel port board due to the lack of opto-
isolation, but the newer design should do the job. I went with the
Bob Campbell/Soundlogic board.

If Steve started selling PCB's I might well consider making another
controller!
