Add individually addressable red, green, blue and white pixels to costumes, signs, props and ambient lighting projects. Each NeoPixel contains separate RGB and white emitters, so you can create colourful effects as well as cleaner white highlights from the same flexible strip.
This version has a white PCB and white casing, with 30 LEDs per metre. The strip is made from flexible PCB material with weatherproof sheathing, and it can be cut at the marked cut-lines or joined to other strips if your power supply can handle the current.
NeoPixels use a timing-sensitive 800 KHz data protocol and need only one digital output pin for control. The PWM is handled inside each LED, so once the colour is set the strip continues driving the LEDs without constant updates from your microcontroller.
Adafruit provides NeoPixel library support for RGBW strips, along with tutorial material, wiring guidance, power calculations and example code for boards including Arduino UNO/Duemilanove/Diecimila, Flora/Micro/Leonardo, Trinket/Gemma, Arduino Due and Arduino Mega/ADK. Make sure your library supports RGBW NeoPixels; a plain RGB NeoPixel library will give incorrect results.

Jargon buster
Plain-language definitions for the technical terms used above.
- Colour depth
- Colour depth describes how many different colours a display can show. A 65K-colour display can show about 65,000 colours, which is useful for icons, graphs, and simple full-colour interfaces but is less detailed than modern phone or computer screens.
- 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.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- 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.
