Adafruit DotStar Digital LED Strip - White 144 LED/m - 0.5 Meter Arduino Kit 24 page downloadable build guideThese fancy DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something even better. DotStar LEDs use generic 2 wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there's no specific timing required. They also have much higher PWM refresh rates, so you can do Persistence of Vision (POV) and have less flickering, particularly at low brightness levels.
