I hope this is the correct place to seek help hooking up my add on laser.
I purchased this kit from E-bay
https://www.ebay.com/itm/PWM-Laser-E...item3d7c7dd79e

It came with a small driver board and no instructions. I am running a usb to BoB to machine. My control software
is UCCNC. Here is a picture of the driver board. I would like to set it as PWM.

If there is and I am sure there is a better driver board please supply a link.

I will answer all questions.

Thank You
Don
