NeoPixel Ring – 16 x WS2812 5050 RGB LED with Integrated Drivers

NeoPixel Ring – 16 x WS2812 5050 RGB LED with Integrated Drivers


In stock


NeoPixel Ring con diametro esterno da 44.5mm, 16 LED smart con chip WS2812 integrato, controllabili in modo indipendente tramite un microcontrollore (AVR, Arduino, PIC, mbed ecc con un clock di almeno 8MHz). Ogni LED richiede circa 18mA di corrente costante, non è richiesta alcuna resistenza aggiuntiva per il funzionamento. Alimentabile con 5VDC. È possibile collegare a catena più NeoPixel Rings.

Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75″ (44.5mm) 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 (4-7V works) 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 microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Our wonderfully-written Neopixel library for Arduino 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.

Comes as a single ring with 16 individually addressable RGB LEDs assembled and tested.
