Adafruit DotStar LED strips use 2-wire SPI instead of the single-wire protocol used by NeoPixels, allowing much faster data rates (up to 32 MHz) and a 20 KHz PWM refresh rate. This makes DotStars ideal for persistence-of-vision (POV) projects and smooth, flicker-free animations — especially at low brightness levels.
Each 5050-sized DotStar LED contains an embedded controller with 24-bit colour (8 bits per channel). LEDs act as shift registers, so you can chain as many as you need. The separate clock and data lines mean any microcontroller or SBC can drive these strips without timing-critical code.
Key Features
- 144 LEDs per Metre – High-density strip on black flexible PCB
- 2-Wire SPI Interface – Clock + data, up to 32 MHz, no timing-critical code needed
- 24-Bit Colour – 8 bits per channel (red, green, blue) per LED
- 20 KHz PWM – Smooth, flicker-free output even in motion
- Weatherproof Sheathing – Protective outer coating
- Cuttable – Cut lines every 1 LED
- 4-Pin JST SM Connectors – One on each end for easy chaining
Also Available
Ideal For
- Persistence-of-vision (POV) displays
- High-density LED art and wearable projects
- Smooth animations and colour effects
Package Contents
- 1× DotStar LED Strip, 144 LED/m, 1 metre (Black PCB) with JST SM connectors
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.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- 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.
- 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.
