Just build a hobbycnc board about 4 or 5 months ago, I don't think it is the new version. I was planning on running it with a 48v power supply that I was able to turn down to 42v which was the published max voltage for the board, but I have seen some post in the past few weeks about 42v burning out the chip?
Should I be concerned? Is there a way to add the chip protection to older designs?
Thanks all,
