These through hole RGB LEDs with an internal chip for serial communication and are different from regular RGB LEDs. Each one contains a tiny microprocessor allowing them to be daisy chained in a linear network where every LED is individually addressable through a one wire communication protocol. Each LED can be individually controlled on the bus.
-Chip built In to the LED for serial control – compatible with WS2812/ws2811 libraries
-Individually control RGB color and brightness of each LED
-Diffused design makes colors soft, pleasing and uniform
-Fast and Responsive
– Easy to hook up with only four pin design: Positive, Negative, Data-In, Data-Out
-The four pins dissipate heat to keep these LEDs cool
-No external resistors or chips needed
-Works with the WS2811/ws2812 Neo Pixel libraries – use with an Arduino, AT-Tiny, Spark-Core, etc

Note the Data IN, Data Out, and Positive, and Negative locations are different than the PixelBit v1.0. You can now more easily chain these LEDs.
if placed in holes with 0.1 inch space, there is approximately 5 mm between the circuit board and the LED body.
Minimum supply voltage 4.5 V
