Update: I was having trouble with the same board that had the misplaced resistor. Durring a simple jog opperation, the motor was not exactly where it should be. After troubleshooting, I found that though the “step” pin appeared to be soldered correctly there was not always a closed circuit from it to the IC “step” pin. Couldn’t see any visable problems with the trace or solder poionts. Once a jumper wire was soldered in place, it worked like the other two.
I just got three of these for a mini cnc project and they work great with the ROB-09238 stepper motor! I noticed that one of the surface mount resistors was not placed correctly, but some quick soldering fixed it just fine. Definatly a great low cost project driver that I’ll get again for future projects.

Well, even if you have to change your name to nerdvirgin.com, I’ll still spend my hard earned money here… although I would prefer not to see that on my credit card statement.
No public wish lists :(
