A while back there was a long
discussion about L297/L298 stepper motor drivers...
I was doing some schematics and had the chance to draw up a schematic in Eagle of the one I built ... perhaps someone has the time/inclination to draw up a PCB "shield"? The schematic in Eagle and PDF format, along with a parts list, are
here in the Playground. It's basically the same as the manufacturer's schematics, with a bunch of caps added for power supply filtering, and the appropriate Arduino pins connected.
