I may not be posting this in the right place, and I'm very new to controlling RGB Pixels, but I'm trying to do my homework and figure out which is better (hate to use that term), more popular, easier to interface/control, etc. I'm interested in the ECG682 and the ECG-P12S boards. The ECG board costs more. Am I talking apples and apples here or apples and oranges? Is it worth the difference? Still confused.
