The USB specification limits current consumption to a max of 500mA from a USB port but this is more than enough to run a simple development board

SparkFun LED - 10mm Cycling RGB (slow) Oscillators This device is also suitableThese color changing LEDs take the work out of creating crazy, flashy, blinky ness. Simply apply power and the LED will cycle through the RGB colorspace: no external controller necessary! These bright and festive LEDs make great decorations, LED throwies, indicator lights, etc. Typical forward voltage is 2V. These 10mm LEDs are of the slow changing variety, meaning they cycle at a rate of one color every few seconds. Documents: Datasheet LED Tutorial
