Adafruit NeoPixel Digital RGBW LED Strip - White PCB 144 LED/m [1m]

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

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

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
