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.
- 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.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- 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.
- 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.
