Is there a KiCad symbol and footprint for the CH482X?
Yes. The symbol is EasyEDA_Cloud:CH482X and the footprint EasyEDA_Cloud:VFQFN-20_L4.5-W2.5-P0.5-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH482X?
QFN-20(2.5x4.5), with 21 pins. Its footprint is drawn on this page.
Where is the CH482X datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH482X?
JLCPCB lists it as part C2913011, with 5,949 in stock; the sellers' links on this page open their listings.
What can replace the CH482X?
Parts like it in the library: the CH482D by WCH (Nanjing Qinheng Microelectronics). Check their datasheets: a part that fits the footprint may still differ in its ratings.
