Hi to the list,
Has anyone used this board?
The SGS-Thomson L297/L298 based chopper drive PCB provides the means to
drive a two phase stepper motor in bipolar mode providing up to 2 amps
of drive per phase with a supply voltage up to 40 volts. This is
provided on a board that measures 2" by 2 3/4".
Board available at:

I'm not connected in any way, but at about $39 an axis, might be worth
considering.
