Now more and more LED Chip with driver come out ,such as WS Series (WS2812B,WS2813,WS2812S)，APA Series (APA102,APA104,APA106), SK Series(SK6812,SK6822,SK9822).

      Normally WS2812B RGB 5050 is compatible with APA104, SK6812 5050 RGB,and can use same controlleR and PCB  , ,SK9822 is compatible with APA102, ,WS2812B mini is not compatible 

with SK6812 mini on same PCB , ,WS2813 led is not compatible with SK6822 on same pcb , as WS2813 led strip no need capacitance , the capacitance is pacakge in the 5050 led chip , 

SK6822 LED strip need capacitance .WS2812S is 6legs which only legs is different WS2812B, and SK6812 5050 RGB have 6legs. APA102 and SK9822 frequency speed is the faster than another .

as they have clock and data. WS2813 and sk6822 is dual signal led ,when you use those led chip to make led strip , one led broken will not affect another . APA106 is F5 F8 dip led . 

and SK6812 not only have rgb ,but also have RGBW ,WWA ,RGBY Color .
