Yeah, I couldn't kill it. If you must have a bipolar driver in that power range and you can't afford a GeckoDrive, this is the chip I would try. I'm considering making a kit available, but haven't see a lot of interest yet... everyone seems to be quite happy flushing money down the toilet on those cheap TB 6 5 6 0 drives from ebay, and you can't fight stupid.
