These RGB LEDs display any colour and have inbuilt WS2812 control IC so they can be addressed via single wire. A rainbow of colour with diffused lens. Sold in packs of 5.
Like the WS2812B breakout board this LED can show any colour of the rainbow and be chained together to make an addressable multicolour light show. This LED has the WS2812 control chip inside the package so no external components are needed. Just hook up an Arduino and make colour. Check out the hookup guide from SparkFun for how to use this little light wonder.
