LED Ring Lamp 4 Bit WS2812 5050 with Integrated Drivers 5V DC 5.3CM/2IN 8.5CM/3.35IN

ONLY FOR AVR CORES---Our wonderfully-written library supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required 24 ULTRA BRIGHT SMART LED---24 ultra bright smart LED are arranged in a circle with 2.6" (66mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one micro-controller pin to control as many as you can chain together! 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. NO EXTERNAL CHOKE RESISTORS---This neopi ring 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. Each LED is addressable as the driver chip is inside the LED JUST 5V DC POWER---The neopi led ring powers the whole thing with 5VDC and you're ready to rock. 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 micro-controller such as an AVR, PIC, mbed, etc
