This 24-LED NeoPixel Ring features RGBW LEDs (red, green, blue, and cool white ~6000K) in a compact circular form factor with a 65.5 mm outer diameter. Each LED contains an integrated WS2812-style driver, so you only need a single data pin from your microcontroller to control all 24 individually addressable LEDs with 32-bit colour (8-bit PWM per channel × 4 channels).
The rings are chainable — connect the data output of one ring to the input of another to build larger displays. Each LED draws ~18 mA constant current for consistent colour regardless of voltage variation, and no external resistors are needed. Power the ring with 5V DC and you're ready to go.
Key Features
- 24× RGBW LEDs – 5050-size with integrated drivers and cool white (~6000K) channel
- Individually Addressable – Control each LED's colour and brightness independently
- 32-Bit Colour – 8-bit PWM per R, G, B, and W channel
- Single-Pin Control – Only one digital output pin required (800 kHz protocol)
- Chainable – Connect multiple rings in series from a single data pin
- Constant Current Drive – ~18 mA per LED for consistent colour output
- 65.5 mm Outer Diameter – Compact circular ring layout
- ~400 Hz PWM Rate – Smooth for stationary applications
Ideal For
- Task and workbench lighting with cool white tones
- Wearable electronics and costume lighting
- Status indicators and circular displays
- Arduino, Raspberry Pi, and microcontroller projects
Package Contents

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
