Product Description:

16 x WS2812b 5050 RGB D55 LED pixel ring

16 ultra bright smart LED Pixels ws2812b are arranged in a circle with 55mm outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another.  Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC. 

There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller.
