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.
- 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.
- 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.
