Good evening. My Gecko 540 recently died. I tried to make repairs, but it was more than just the two output MOSFETs. I am trying to go with some other driver for my CNC. They are the same ones I am using on my laser engraver, and they seem to work well. I just have a question on the on-the-power to them. I am using the driver that is attached to this post. My question is for the Pull+ and Dir+: do I have to use 5V, or can I use 12V? I am coming directly off of a breakout board from the UC300ETH to the drivers. I don't want to put like 12V and fry my UC300ETH. Right now, I am using 5V because I have a 5V converter.

Thanks,
Justin
