12-LED RGBW NeoPixel Ring (Warm White) with individually addressable pixels, 32-bit colour control, and a dedicated white channel. Chainable, 5 V powered, and controlled from a single pin — perfect for compact, high-impact lighting projects.
What’s better than smart RGB LEDs? Smart RGB + White LEDs! This 12-LED RGBW NeoPixel Ring (Warm White) adds a dedicated white LED to every pixel, giving you richer colours, cleaner whites, and far more flexible lighting effects — all arranged neatly in a circle.
The ring measures 1.45″ (37 mm) in outer diameter and features 12 ultra-bright, individually addressable NeoPixels. Each LED contains its own driver chip, so every pixel can be controlled independently using just one microcontroller pin. The rings are fully chainable, letting you connect multiple rings together by linking the data output of one to the input of the next.
Each NeoPixel includes constant-current drive (~18 mA per channel), ensuring consistent colour even if the supply voltage varies. No external resistors are needed — simply power the ring from 5 V DC, and you’re good to go.
Each pixel is “split” internally: one half provides the familiar RGB, while the other is a warm white LED with yellow phosphor. Unlit, the white element looks a bit like an egg yolk, but once powered it’s extremely bright. Brightness and colour are controlled using 8-bit PWM per channel, giving 32-bit colour control per pixel. This makes the ring ideal for smooth colour blends, warm white illumination, or combining both in a single animation.
NeoPixels use an 800 kHz single-wire protocol, which requires accurate timing. The PWM refresh rate is around 400 Hz, which works well in most cases but can be noticeable if the LEDs are moving. For higher-speed visual applications, DotStars offer a 20 kHz PWM rate, though NeoPixels remain a great choice for most projects.
Because the PWM engine runs inside each LED, once you send the colour data, the ring continues driving the LEDs on its own — no constant updates required. Control data is passed along the ring using an internal shift-register design, allowing an effectively unlimited number of chained pixels.
Extensive documentation is available, including wiring guides, power calculations, and example code. Be sure to use a NeoPixel library with RGBW support — standard RGB-only libraries will not work correctly. The Adafruit NeoPixel library fully supports RGBW devices, and the NeoPixel Überguide covers everything from basic setup to advanced animations.
Each ring is fully assembled and tested and includes 12 individually addressable RGBW NeoPixels.

Revision History
As of November 1, 2023 – we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.
