  • Caution: Do not connect or disconnect a motor while the driver >is energized. This will cause permanent damage to the A3967 IC.
    I probably did this while I was searching right cables. Now when I plug my step motor it makes this sound like it’s working (but not) instead it vibrates randomly.
    any suggestion for testing A3967 to see if it is really gone or not

  • Mine just arrived. The upper claw was broken. I don’t want to waste my time with returning it. Just figure out a better closure.

No public wish lists :(
