Questions

Is there a KiCad symbol and footprint for the WS2811C?

Yes. The symbol is Driver_LED:WS2811 and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the WS2811C?

SOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the WS2811C datasheet?

Worldsemi publishes it: the Datasheet link on this page opens it.

Where can I order the WS2811C?

JLCPCB lists it as part C2920043, with 11,151 in stock; the sellers' links on this page open their listings.

What can replace the WS2811C?

Parts like it in the library: the RT9284A-20GJ6E by Richtek Tech, the TLC5916IPW by Texas Instruments, the STP16CP05T by STMicroelectronics and the STP16CPC26P by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the WS2811C?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
