Adafruit NeoPixel Ring - 16 x 5050 RGB LED with Integrated Drivers [ADA1463]

Round and round and round they go 16 ultra bright smart LED NeoPixels are arranged in a circle with 175 445mm outer diameter The rings are chainable connect the output pin of one to the input pin of another Use only one microcontroller pin to control as many as you can chain together 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 47V works and youre ready to rock There is a single data line with a very timingspecific protocol Since the protocol is very sensitive to timing it requires a realtime microconroller such as an AVR Arduino PIC mbed etc It cannot be used with a Linuxbased microcomputer or interpreted microcontroller such as the netduino or Basic Stamp Adafruits wonderfullywritten Neopixel library for Arduino supports these pixels As it requires handtuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around Item Specifics Outer diameter 445mm 18 Inner diameter 317mm 12 Thickness 67mm 03 Weight 303g Single ring with 16 individually addressable RGB LEDs An 8MHz or faster processor is required May ship with either WS2812B or SK6812based LEDs They are the same brightness color and protocol
