An ultra-high-density NeoPixel strip packed with 144 individually addressable RGB LEDs per metre on a flexible white PCB with white mask. Each pixel offers full 24-bit colour control, and only a single data pin is needed to drive the entire strip. Also available with a black PCB.
The strip comes in a 1-metre length with weatherproof sheathing (removable if not needed) and JST SM connectors on each end for easy chaining. The white PCB blends naturally into light-coloured surfaces and enclosures.
Key Features
- 144 RGB LEDs per Metre – Maximum pixel density for seamless colour blending and smooth animations
- Individually Addressable – Set each LED's colour independently with 8-bit PWM per channel (24-bit colour)
- Single-Pin Control – Only one digital output pin required; built-in PWM controller in each LED maintains colour without continuous data
- White PCB + White Mask – Blends into light-coloured surfaces and enclosures
- Weatherproof Sheathing – Included silicone sleeve for weather resistance (removable with scissors)
- Chainable – JST SM connectors on each end for extending or shortening
- Cuttable – Cut between any two LEDs with wire cutters; solder to 0.1" copper pads
Power Requirements
- Voltage – 5V DC (do not exceed 6V or the strip will be damaged)
- Max Current – ~7A at full white (35W per metre)
- Typical Current – Colourful patterns typically draw 1/3 to 1/2 of maximum
Warning: You must use a 5V DC power supply to power these strips. Do not exceed 6V or you risk destroying the entire strip. A quality 5V 10A power supply is recommended.
Compatibility Notes
- Works with Arduino (8 MHz+), Raspberry Pi, ESP32, and other fast microcontrollers
- Requires precise 100 ns timing — not compatible with interpreted platforms (Basic Stamp, NETduino) or processors slower than 8 MHz
- Each LED requires 3 bytes of RAM — budget approximately 432 bytes for the full metre (Arduino Uno has ~1,500 bytes free after libraries)
- For processors without strict timing capability, consider DotStar LED strips which use SPI-based control
Ideal For
- High-density light bars and ambient lighting
- LED art installations and props
- Cosplay and wearable projects
- Light-coloured enclosures and displays
Package Contents
- 1× NeoPixel Digital RGB LED Strip – 144 LED/m, 1 metre, white PCB
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.

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- ESP32
- ESP32 is a family of low-cost microcontroller chips and modules from Espressif with built-in WiFi and Bluetooth. They support programmable firmware and over-the-air updates, and are commonly programmed with toolchains such as the Arduino core and ESP-IDF.
- 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.
- 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.
- RAM
- RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
- 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.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
