I know there are:
- color cycling (loop with the darlington array)
- column cycling...
so
at a T time, the maximum is one color of 8 leds on...
nobody at sparkfun wants to tell me more about that...
if I was sure, I'd use only the usb power supply
as I'm not, I'll use the 5V 2,5A power supply I got.
so... if the amperage was about 1 - 1,5 ... I don't know if 32 mil would be enough... how could I know that?
