{"title":"Adafruit NeoPixel Ring - RGB LED w/ Integrated Drivers - 16 pixel","handle":"adafruit-neopixel-ring-rgb-led-w-integrated-drivers-16-pixel","url":"/products/adafruit-neopixel-ring-rgb-led-w-integrated-drivers-16-pixel","description":"Round and round they go! 16 ultra-bright smart RGB NeoPixels are arranged in a circle with a 44.5 mm (1.75″) outer diameter. Each LED is individually addressable from a single microcontroller pin, delivering 24-bit colour with ~18 mA constant-current drive for consistent brightness regardless of voltage variation.\n\nThe rings are chainable — connect the output pin of one ring to the input pin of another to build larger displays. Also available in 12-pixel and 24-pixel RGB sizes, plus 16-pixel RGBW variants with a dedicated white channel.\n\nKey Features\n\n\n16 RGB LEDs – Individually addressable WS2812-compatible NeoPixels in a circular arrangement\n\nMedium Form Factor – 44.5 mm (1.75″) outer diameter, slim profile with no external resistors required\n\n24-Bit Colour – 8-bit PWM per channel (R, G, B) for over 16 million colours\n\nConstant Current Drive – ~18 mA per LED for consistent colour even with voltage variation\n\nSingle-Pin Control – One data line drives all 16 LEDs using the NeoPixel protocol\n\nChainable – Connect output of one ring to input of the next for larger installations\n\n\nPower Requirements\n\nSupply voltage: 5 V DC (4–7 V working range)\nMaximum draw: ~60 mA per pixel (up to ~960 mA at full white for the entire ring)\n\n\nCompatibility\n\nWorks with real-time microcontrollers: Arduino (AVR, SAMD, nRF52), ESP32, ESP8266, Teensy, and more\nRequires 8 MHz or faster processor\nSupported by Adafruit's NeoPixel library (Arduino) and CircuitPython/MicroPython neopixel module\nNot compatible with Linux-based SBCs or interpreted platforms (e.g., Basic Stamp) for direct driving\n\n\nIdeal For\n\nWearable electronics and jewellery\nStatus indicators and gauges\nCircular animations and colour-cycling effects\nIoT device feedback rings\nCosplay and costume accents\n\n\nPackage Contents\n\n1× Adafruit NeoPixel Ring – 16 RGB LEDs, assembled and tested\n\n\nResources\n\n\nNeoPixel Uberguide – Comprehensive guide covering wiring, libraries, and example code\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8983,"title":"Default Title","sku":"AF-1463","price":21.08,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
