This laser is bright as Sh*t the controller works very good but it takes some doing to get it work with the Arduino Nano Controller board version I have because the output pins are NOT marked only the laser controller is marked correctly no issues with this part now on the Arduino Nano board is another story in the pictures of this Nano board controller it laser output but does not show which pin is which the only thing I could do use a meter to figure out what pin does what I also found that laser output is 0 to 5 volts output that the laser controller needs to work correctly as you can see in the picture the wire that is not connected is the PWM output wire one note the output that says that it is PWM output is 0 to 12 volts not the 0 to 5 volts like the other output connector one other note when the TTL output is selected I find that it does not control as well as the PWM signal does it might just be me

Once I found the PWM signal output pin it works very well but I have not yet engraved with yet because I have not finished building my engraving machine yet but hopefully in a couple of weeks from now I hope be engraving soon with the laser and the spindle But this laser controller is worth the money I would highly recommend if you have a laser that does not have a controller
