What Are DotStar LEDs (APA102/SK98225)? - Tutorial Australia
They operate over a generic 2-wire SPI bus which removes the need for a finicky transfer speed and allows for data transfer at 8-32Mhz rather than 800Khz. The APA102 chip uses PWM rates of 19.2Khz which allows DotStar LEDs to be used in Persistence of Vision (POV) displays and smoother PWM fading. However instead of only requiring a single pin to transfer data, the DotStar LEDs require two, so let’s take a look at how to use them.

Note that even the Adafruits NeoPixel Uberguide recommends FastLED for advanced use. Some of their tutorials use it instead of the NeoPixel library.
