WS2812B "Neopixel" RGB LED, 25 pack

WS2812B RGB LED, 25 pack of individual LEDS in cut tape-and-reel strips. Great for adding color to your Arduino project. These LEDs have a built-in driver and data-in, data-out pins that allow them to be strung together serially into long runs. Pads are exposed on the sides for easy soldering. This is the four pin 'B' version. The primary difference between this and the WS2812S (six pin) is pinout. See Data sheet for implementation details. http://electron14.com/wp-content/uploads/2014/09/WS2812B.pdf
