An ultra-high-density RGBW NeoPixel strip with 144 individually addressable LEDs per metre on a flexible white PCB. Each pixel contains four LED elements — red, green, blue, and a dedicated white — providing 32-bit colour control and superior white output compared to RGB-only strips. Also available with a black PCB.
The dedicated white LED with yellow phosphor produces clean, bright white light without colour mixing artifacts. The white PCB blends naturally into light-coloured surfaces and enclosures.
Key Features
- 144 RGBW LEDs per Metre – Maximum pixel density with dedicated white element for true white output
- 32-Bit Colour – 8-bit PWM per channel across 4 channels (R, G, B, W) for over 4 billion colour combinations
- Individually Addressable – Control each LED independently with single-pin data
- White Flex PCB – Blends into light-coloured surfaces and enclosures
- Weatherproof Sheathing – White protective casing included (removable)
- Chainable & Cuttable – JST SM connectors on each end; cut between any two LEDs
- 5050-Sized LEDs – Integrated microcontroller inside each LED package
Power Requirements
- Voltage – 5V DC (do not exceed 6V or the strip will be damaged)
- Max Current – Higher than RGB strips due to the additional white channel; use a robust power supply
- Recommended Supplies – 5V 2A supply for 1 metre (depending on usage); 5V 10A supply for brighter patterns or chained strips
Warning: You must use a 5V DC power supply to power these strips. Do not exceed 6V or you risk destroying the entire strip.
Compatibility Notes
- Works with Arduino (8 MHz+), Raspberry Pi, ESP32, and other fast microcontrollers
- Uses 800 KHz protocol with ~400 Hz PWM refresh rate
- Each LED requires 4 bytes of RAM (vs 3 for RGB) — 144 LEDs uses 576 bytes
- Requires an RGBW-compatible NeoPixel library — using a standard RGB library will produce incorrect results. The Adafruit NeoPixel library supports RGBW mode
- The blue LED element is adjacent to the white phosphor, so blue light may have slight white bleed
Note: There is a join in the middle of the strip where LED spacing may not be perfectly even — this is a manufacturing tradeoff at this pixel density.
Ideal For
- High-quality white lighting combined with full colour effects
- Architectural and ambient lighting where true white matters
- LED art installations requiring both colour and white
- Light-coloured enclosures and displays

Jargon buster
Plain-language definitions for the technical terms used above.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- 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.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- 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.
