DotStar Digital LED Strip (30 LED/m)
Overview
The Adafruit 2432 is a 1-meter addressable LED strip featuring 30 DotStar (SK9822) RGB LEDs. Unlike traditional NeoPixels, these LEDs use a two-wire SPI-like protocol with separate data and clock lines, allowing for much higher data rates and less strict timing requirements.
Why Choose This Part
The separate clock line eliminates the need for the tight, interrupt-free timing required by WS2812B LEDs, making these more robust for use with multitasking operating systems. They offer a higher PWM refresh rate (up to 1.2 kHz), significantly reducing flicker in filmed environments or moving displays.
Applications
Getting Started
Connect the strip to a 5V power supply capable of handling up to 2A per meter and interface the SDI and CKI pins to your MCU hardware SPI port or any two digital pins. Use the Adafruit_DotStar library for Arduino or the CircuitPython DotStar module for rapid development.
