  • A lot of people have had questions about torque, direction, speed etc. with these. I’ve learned from experience that the general answer to this has to do with the current. Be sure there’s not too much or too little current; it can generally be adjusted with a little pot on the stepper motor driver, like the EasyDriver.

  • I have two of these. When A and B are connected to a common ground, and the A side has 3.3V (on VccA and A1) and the B side has 4.65V on VccB, the output on B1 is always around 2.2V. What am I missing?

  • I think I just wired this thing up wrong, even after checking everything with a meter. A pin diagram is really needed.

No public wish lists :(
