The SK6812 LEDs are very similar to the well known WS2812 and are driven in the same manner. Each pixel on this strip has, in addition to the traditional RGB LEDs, an extra “white” LED which enables a better color rendering than the R+G+B combination. It looks like any other addressable strip, but instead of 3 channels of color (24 bit), you load in an additional 4th channel for the white for a total of 32 bits per LED. This sort of data load may require careful use on microcontrollers with little RAM (460 LED limit for an Arduino UNO).
NOTE: Being RGB/W means many standard Arduino addressable LED libraries are not entirely compatible. Until then, keep an eye on these libraries that do support it:
