The Adafruit DotStar Digital LED Strip (144 LED/m, white flex PCB) delivers superior performance over traditional NeoPixels with its 2-wire SPI interface. Push data at up to 32 MHz clock speed with no critical timing requirements, making it compatible with virtually any microcontroller or microprocessor.
Each 5050-sized RGB LED contains an embedded driver chip that handles 24-bit colour output and 20 KHz PWM — ideal for persistence-of-vision (POV) projects and smooth, flicker-free colour blending even at low brightness levels. This is a 0.5-metre length of the ultra-dense 144 LED/m strip on white flex PCB.
Key Features
- SPI Interface – 2-wire (clock + data) protocol works with any processor speed; no timing-critical code required
- 24-Bit Colour – 8 bits per channel (red, green, blue) for over 16 million colours
- 20 KHz PWM – 50× faster than NeoPixel's 400 Hz for flicker-free operation and smooth POV effects
- Up to 32 MHz Data Rate – Hardware SPI supported but not required
- Ultra-Dense 144 LED/m – Seamless light output with no visible gaps between LEDs
- Weatherproof Sheathing – Flexible PCB with protective coating
- Cuttable – Cut lines every 1 LED, solder to 0.1" copper pads
- 4-Pin JST SM Connectors – Included on each end

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.
- 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.
- 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.
