Questions

Is there a KiCad symbol and footprint for the R818?

Yes. The symbol is EasyEDA_Cloud:R818 and the footprint EasyEDA_Cloud:LFBGA-346_L12.0-W12.0-P0.50-TL_ALLWINNER_A133, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the R818?

LFBGA-346(12x12), with 346 pins. Its footprint is drawn on this page.

Where is the R818 datasheet?

Allwinner Tech publishes it: the Datasheet link on this page opens it.

Where can I order the R818?

JLCPCB lists it as part C5720369, with 339 in stock; the sellers' links on this page open their listings.

What can replace the R818?
