Cheap CNC breakout board for controlling spindle speed, will this work?

[A_Camera]

I still would like to see one of these cheap boards functioning at all, not to mention properly with mach3

I have two of these and they both work very well with Mach3 and UC300. The only issue is that I can't get 10V out of the DA converter, the top voltage is 9.6V so I can't get the spindle to run at full speed with it. I don't know if that matters a lot later on, still using the 400W DC motor and my spindle is still under test, not installed yet.

Edit:

What I also forgot to mention regarding the 10VDC output is that apart from the output never reaching 10V, it is also not very linear. So if you want to have precise control of the spindle RPM then this BoB won't be good enough, or must use a separate, better PWM 0-10VDC converter.

I have one of these that I might try out, is there a wiring diagram available for it?
