Hoping someone can help to ID this Breakout board. I bought it years ago from Keling but have lost the wiring of it. I'm in the process of wiring up my new 2.2kv spindle and purchased a cnc4pc C6 speed controller. Now after looking at the board I realized it has a relay so thinking I can use my existing Breakout Board and wire direct to VFD. Only problem is it is labeled poorly and need a wiring diagram. Can anybody ID this make of Board and supply a wiring diagram to wire to Huanyang VFD. Take notice it is a DB25 and USB which I use to power the board from the computer.

Thanks in advance
Steve
