The Adafruit DotStar APA102 Cool White LED Strip (30 LED/m, ~6000K) uses the same integrated DotStar driver as the RGB strips but with dedicated cool white phosphor LEDs. The result is an incredibly bright, consistent white light — far superior to mixing RGB to approximate white.
Controlled via a 2-wire SPI interface at up to 32 MHz, each LED features 24-bit PWM brightness control at 20 KHz for smooth, flicker-free dimming. No timing-critical code is required, making these strips compatible with any microcontroller or microprocessor. This is the 30 LED/m density on white flex PCB, sold from 5-metre reels.
Key Features
- Cool White ~6000K – Dedicated white phosphor LEDs for true, consistent white light
- SPI Interface – 2-wire (clock + data) protocol works with any processor speed
- 24-Bit Brightness Control – High-frequency 20 KHz PWM for smooth, flicker-free dimming
- Up to 32 MHz Data Rate – Hardware SPI supported but not required
- Weatherproof Sheathing – Flexible PCB with protective coating
- Cuttable – Cut lines every 1 LED, solder to 0.1" copper pads
- Chainable – Connect strips together for longer runs
- 4-Pin JST SM Connectors – Included on each end of full reels

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.
- 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.
