Add individually addressable RGB plus white lighting to your project with this flexible NeoPixel strip. Each pixel contains red, green, blue and white LEDs, giving you colourful effects plus a dedicated white channel for brighter, cleaner white output.
This version has 60 LEDs per metre, a clear weatherproof sheathing and a white flexible PCB. The strip can be cut at the marked cut-lines, soldered to the 0.1" copper pads, or joined to other strips to make longer runs, provided your power supply can handle the current.
NeoPixels use an 800 KHz single-wire protocol, so only one digital output pin is needed for data. The PWM is handled inside each LED package, so once colours are set the strip continues driving the LEDs without constant updates from your microcontroller.
Adafruit’s NeoPixel library supports RGBW strips, and the NeoPixel Uberguide includes wiring help, power calculations, library support and example code for boards such as Arduino UNO, Flora, Micro, Leonardo, Trinket, Gemma, Arduino Due and Arduino Mega/ADK.

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.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- 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 (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- 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, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
