16-LED RGB Circuit Ring – WS2812B (Black PCB)

Bring dynamic, colourful effects to your wearable projects with this 16-LED WS2812B RGB circuit ring on a bold black PCB. LEDs are spaced closely together for extra smooth, vivid animations — I used a version of this in my physical distancing hat project (check the photos!).

Just three connections: Ground, Power, and Data. Works with FastLED, Adafruit NeoPixel library, Arduino, ESP32, and any WS2812B-compatible platform. Comes pre-wired and ready to connect.
