RE: Now is world of individually Addressable LED, just like SK6812. Have a lot of applications. just like use in shoe, car light, led stripposted in Omega Talk
You can use sk6822 led or ws2813 led ,their has 2 data signal,any pixel’s failure won’t affect signal transfer unless two consecutive adjacent LED are Broken.

RE: Individually Addressable SMD led, Just like WS2812, But it also have another SMD led, SK6812, About its controller way, here have someone know.posted in Omega Talk
ws2812 led has the same protocol with sk6812 led,so they can be controlled by the same controller.

RE: here have some data of ws2813 5050 led ,which is better than ws2812b sk6812 rgb ledposted in Omega Talk
WS2813 led is update ws2812b led is dual signal ,signal break out contious transmission.
sk6812 led is the same with ws2812b,but it's better than ws2812b,much stable.
