Ultra-compact NeoPixel RGB LEDs in a tiny 2427 package (2.4 × 2.7 mm) — half the size of 3535 Mini NeoPixels and a quarter the size of standard 5050 NeoPixels. Each LED contains red, green, and blue elements with an integrated driver chip that handles constant-current PWM, so colour remains consistent even as voltage varies.
Like all NeoPixels, these are chainable — the output of one LED feeds into the input of the next, allowing near-infinite chain lengths from a single data line. Set each LED's 24-bit colour once and the driver handles the rest.
Key Features

- Integrated Driver Chip – Constant-current drive with 24-bit colour (8-bit per channel)
- Chainable – Data output cascades to the next LED for long chains
- No External Resistors – Constant-current drive eliminates the need for choke resistors
- RGB – Three LEDs (red, green, blue) in each package

Jargon buster
Plain-language definitions for the technical terms used above.
- Colour depth
- Colour depth describes how many different colours a display can show. A 65K-colour display can show about 65,000 colours, which is useful for icons, graphs, and simple full-colour interfaces but is less detailed than modern phone or computer screens.
- 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.
- SMD
- SMD means surface-mount device, a component style designed to be soldered directly onto the surface of a circuit board rather than through holes. SMD parts are compact and mounted flat on the board, which suits smaller and mass-produced designs.
