Arduino PWM LDD Driver Question.

[ghellin]

I have an arduino duemilanove set up that I want to control a several Meanwell LDD drivers with. Since I want more PWM outputs than the board can supply I need to add a PWM breakout board. I found this one and I wanted to know if this would suffice for precise dimming.

And a few small other questions.
1. What is the current needed for the PWM signal on the LDD drivers? IIRC the ELN's were really low, just don't remember the range.

2. Since the board will need a power supply for the PWM output would a 5v 200mA do the trick?

That should work fine.

1. What is the current needed for the PWM signal on the LDD drivers? IIRC the ELN's were really low, just don't remember the range. The LDD's only pulls current in the micro-amp range, so you're able to drive dozens per pin without worry.

That's plenty of power and will work fine.

Awesome ty!
