 +[[https://cpldcpu.wordpress.com/2014/01/14/light_ws2812-library-v2-0-part-i-understanding-the-ws2812/|some info]] on the data pins and protocol of ws2812
 +
 +>he main difference between the two drivers is that the SK6812 has voltage-independent color and brightness over a wide voltage range, which means that the colors of the LEDs should not be affected by a drop in the supply voltage as much as they are on the WS2812B.[[https://www.pololu.com/category/180/sk6812-ws2812b-based-led-strips|source]]
