The Adafruit NeoPixel 332 LED/m Silicone Bead Strip packs an astonishing 165 miniature SK6812 NeoPixels into a 0.5 m length, coated with a milky silicone bead diffuser for a smooth, continuous colour gradient. At 332 LEDs per metre, this is one of the highest-density addressable LED strips available.
Each LED provides 24-bit colour (8-bit per RGB channel) on a single data line. The SK6812 LEDs work with 3–5 V logic and power (best at 5 V), and don't require an inline resistor. The strip is 14 mm wide on flexible PCB with weatherproof sheathing, and comes with JST SM 3-pin connectors and colour-coded wires (black = ground, green = signal, red = 5 V).
Key Features
- 332 LEDs per Metre – 165 miniature SK6812 NeoPixels in 0.5 m
- Silicone Bead Diffuser – Milky coating produces smooth, continuous colour blending
- 24-Bit Colour – 8-bit PWM per red, green, and blue channel
- Single-Pin Control – One digital output drives the entire strip
- 3–5 V Compatible – SK6812 LEDs work without inline resistor
- Cuttable – Shorten with wire cutters as needed
- Chainable – Connect multiple strips (watch current budget)
- JST SM 3-Pin Connectors – Plug and socket on each end with colour-coded wires
Power Requirements
- Maximum theoretical draw – ~10 A at 5 V for 0.5 m (all LEDs full white)
- Typical draw – Less than one-third of maximum for colourful patterns
- A 5 V 2 A supply is sufficient for colourful designs at moderate brightness
Ideal For
- Ultra-smooth colour gradient effects
- Wearable electronics and costumes
- High-density light painting
- Compact LED art with continuous colour blending
Package Contents
- 1× 0.5 m NeoPixel 332 LED/m Silicone Bead Strip (with weatherproof sheathing)

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- 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.
