best laser install ?

[KevinSant]

I have the duet 2 with rrf3.2.2

this 30-W 12v3a laser would it be best to use a separate power supply and hook up to the fan or or using a buck converter to the center pin fan Vin jumper was also thinking about getting a d u e x board will I be able to directly hook up to that

Do you have any spec sheet for the laser? Schematic for the board? Can you show a better close up photo of the board front and back?
