16-LED RGBW NeoPixel Ring (Warm White) with individually addressable pixels, dedicated white LEDs, and 32-bit colour control. Chainable, 5 V powered, and controlled from a single pin—perfect for circular lighting and animation projects.
What’s better than smart RGB LEDs? Smart RGB + White LEDs! This 16-LED RGBW NeoPixel Ring (Warm White) adds a dedicated white LED to every pixel, delivering brighter whites and more flexible lighting effects in a neat circular layout.
The ring has a 1.75″ (44.5 mm) outer diameter and features 16 ultra-bright, individually addressable NeoPixels. Each LED includes its own driver chip, so every pixel can be controlled independently using just one microcontroller pin. The rings are fully chainable—simply connect the data output of one ring to the input of the next to control multiple rings from a single pin.
Each NeoPixel provides approximately 18 mA constant current drive, ensuring consistent colour even if the supply voltage varies. No external resistors are required, keeping designs compact and simple. Power the ring from 5 V DC and it’s ready to go.
Internally, each pixel is “split”: one half handles 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—ideal for smooth colour blending and warm white illumination.
NeoPixels use an 800 kHz single-wire protocol, which requires accurate timing. The PWM refresh rate is around 400 Hz, which works well for most applications but may be noticeable if the LEDs are moving. For higher-speed visual effects, DotStars offer a 20 kHz PWM rate, though NeoPixels remain an excellent choice for most projects.
Each LED contains an embedded microcontroller and operates like a shift register, passing data from one pixel to the next. Once colour data is sent, the built-in PWM continues driving the LEDs automatically—no constant updates needed.
Comprehensive documentation is available, including wiring guides, power usage calculations, and example code. Be sure to use a NeoPixel library with RGBW support, as 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 ships fully assembled and tested, with 16 individually addressable RGBW NeoPixels.
Specifications
Outer diameter: 44.5mm
Inner diameter: 31.75mm
Thickness: 3.25mm / 0.13"
Weight: 4.2g
May ship with either WS2812B or SK6812-based LEDs. They are the same brightness, colour and protocol
Revision History
As of May 17, 2023 - You may get a NeoPixel Jewel with either WS2812B LEDs or SKC6812 LEDs; they are the same protocol and brightness. However, the SKC are more reliable and handle accidental over-volting a little better!
