It really isn't terribly complex. Changing the sense resistors to one half ohm (or soldering another 1 ohm resistor in parallel) will give you 2 amps. For 2.3 amps, for each coil, you need a 1 ohm (already supplied as R1 or R2), plus another 1 ohm (R3 / R5), plus a 30 ohm resistor (R4 / R6) all soldered in parallel. Make sure your heat sink is a good one!' at: '' mac-one@netscape.com asks:

http://www.call-mac-then-pack.com/hobby.htm Someone must have already revised these boards to put out 2.3 amp. I can solder and thats about it. Trying to get my motors to work like they should, 2.3 volt & 2.3 amp unipolar applied motion products. If I knew what to get I could install it on my boards. Can you please help me. Bought the boards from you and more sales to me are fourthcomming.
