The WS2812B RGB LED is a small size with BIG color. The chip has a special LED on board that contains three separate LEDs (red, green, and blue) as well as a smart IC that can individually control each LED. Each color has 256 intensity levels which allows the LED to produce 24-bit color (more than 16 million colors). Each LED is instructed by using a special serial protocol which allows many LEDs to be daisy-chained together so one microcontroller can control the whole chain with a single data signal. Any number of these LEDs can be chained together by connecting one LED's data-out (DO) pin to the next LED's data-in (DI) pin.
Caution - these LEDs are extremely bright! You might want to avoid looking directly at them up close when lit.

Note: This LED requires a +5V power supply to work. Devices that interface at 3.3V can still communicate with the module, but the module will need to be supplied with 5 volts on the 5V pin. Additionally, the serial communication protocol the module utilizes relies heavily on strict timing constraints. Thus, the BASIC Stamp modules cannot reliably communicate with the WS2812B RGB LED.
