Hi, I want to switch over from a mega to a due. I'm using mean well ldd's on a driver board like this one.

Is there anything I need to do to interface this with a due? Will it output 5v pwm or is 3.3v pwm perfectly fine with the ldd's?
Thanks for the advice
Will it output 5v pwm
No.
is 3.3v pwm perfectly fine with the ldd's?
No idea because of the lack of information on that link but it is probable that it won't be OK and you will need transistors to boost the signal.
The link to the data sheet on that page is broken.
The board just looks like a dip connection for the meanwell Ldd-h with 10 resistors on each so the led's won't go to max brightness when the arduino is off.
The transistors to boost it to a 5v pwm? Would that be the same as using a logic level converter?

Yes a simple transistor will do. Note that if this results in an inverted signal then that is fine too. Instead of the value you would normally use for an analogWrite just use 255 - value .
Ok sounds good I appreciate the help. Now how does pwm work? It's not where 3.3v is max output so the device reads this as max power? Guess I never understood really how pwm works.
Now how does pwm work?
