The 24 LED RGBW NeoPixel Ring – Warm White combines vibrant RGB control with dedicated warm white output in a 2.58" circular layout, fully chainable and driven from a single microcontroller pin for high-impact lighting projects.
What’s better than smart RGB LEDs? Smart RGB + White LEDs. This 24 LED RGBW NeoPixel Ring – Warm White adds a dedicated white channel to the classic NeoPixel design for richer lighting effects and more natural white tones.
This ring features 24 ultra-bright 5050 RGBW NeoPixels arranged in a circle with a 2.58" (65.5mm) outer diameter. The ring is fully chainable — simply connect the output pin of one ring to the input pin of the next. You can control as many as you like using a single microcontroller pin.
Each LED contains an integrated driver chip and provides approximately 18mA constant current drive, ensuring consistent colour even if the supply voltage varies. No external resistors are required, keeping your design compact. Power the ring with 5V DC and you’re ready to go.
Each NeoPixel is effectively split into two sections: the familiar RGB LED, and a separate white LED with a yellow phosphor. Unlit, it resembles an egg yolk. When powered, the output is extremely bright. Each channel is controlled with 8-bit PWM, giving 32-bit colour per pixel (8 bits × 4 channels) for detailed lighting control.
NeoPixels use a single-wire 800 kHz protocol, which requires precise timing. The PWM refresh rate is approximately 400 Hz, which works well for most applications but can be noticeable if the LEDs are moved quickly. In comparison, DotStars use a 20 kHz PWM rate for smoother blending during motion.
Each LED acts like a shift register, passing data along the chain. Once you send colour data, the PWM is handled internally, so the LEDs continue displaying the set colour without further updates.
A NeoPixel library with RGBW support is required. Using a standard RGB-only NeoPixel library will produce incorrect results. The Adafruit NeoPixel library supports RGBW, but other libraries may require modification.
Be sure to check the tutorial for wiring guidance, power usage calculations, and example code.

Revision History
As of Nov 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.
