Need to add little dots of colour to a costume, wearable, or structure? The Adafruit NeoPixel Slim LED Dot Strand uses soft plastic cords of plated wire instead of a rigid PCB, making it easy to embed, sew over, or cast into any project. Each tiny NeoPixel dot is spaced every ~50 mm (~2″) along a 1-metre strand.
Unlike traditional NeoPixel strips that can crack when bent too far, these flexible strands move freely and conform to curves. The wires are PVC-coated and the LEDs are sealed with epoxy dots for light weather resistance. Also see the NeoPixel LED Dots Strand for the original thicker-wire version.
Key Features
- 20 RGB NeoPixels – Individually addressable LEDs at ~50 mm (~2″) pitch along a 1-metre strand
- Slim, Flexible Wires – Soft plastic plated-wire cords that are easy to sew, embed, or cast
- Connectors Pre-Attached – Ready to connect; can also be carefully soldered to the flexible wires
- Cuttable – Trim to any length with standard wire cutters
- Chainable – Connect multiple strands together for longer runs
- Semi-Weatherproof – PVC-coated wires and epoxy-sealed LEDs for temporary outdoor use
Wiring
There are no power/data markings on the strand (no PCB). Identify wires by colour through the translucent coating:
- Red wire – V+ power (5 V)
- Middle wire – Data in
- Last wire – Ground
Power Requirements
- Supply voltage: 5 V DC (do not exceed 6 V or the entire strand may be damaged)
- Maximum draw: ~60 mA per pixel (up to ~1.2 A for the full 20-LED strand at full white)
Ideal For
- Wearable electronics and costumes
- Sewable LED projects
- Embedding in props, structures, and castings
- Curved and irregular surface lighting
- Decorative string lighting
Package Contents
- 1× Adafruit NeoPixel Slim LED Dot Strand – 20 LEDs at 2″ pitch (1 m total length)

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.
- 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.
