Witop Sk6812 vs Ws2812b vs Sk6812 Rgbw Addressable Led Strip

Let we see the clear ws2812b and sk6812 sk6812rgbw addresable led strip first!

 

SK6812 RGB VS SK6812 RGBW:

sk6812 5050 rgbw(RGBWW= RGB + Warm White (2800-3200k),RGBNW= RGB + Natural White (4000-4500k),RGBCW = RGB + Cold White (6000-6500K) ,we can see,it have one more white color than sk6812 5050 rgb led strip,When we do not need rgbw color,it can show white color,However,for,sk6812 5050 rgb,when it show the white color it is red green blue color mix together,so,it is not really white color!

SK6812 VS WS2812B addressable led strip,

The SK6812 is very similar to the WS2812B, and can be used as a drop-in replacement in most applications because it features the same interface and color order (so LED strips based on the SK6812 and WS2812B can be chained together). The 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.

Looks like sk6812 is a direct clone of ws2812b with some improvements made. LED is driven at higher PWM frequency and some variants have separate white die, instead of running RGB channels simultaneously. All existing ws2812 libraries are compatible (commonly refered as ‘NeoPixel’). Sk6812 and ws2812 are actually controler chips, and LEDs you are interested in have chip integrated.

Normally,we can not distinguish it well,but through the IC shape,we can see it is ws2812b or sk6812.
