Is there a KiCad symbol and footprint for the CH390D?
Yes. The symbol is OLIMEX_IC:CH390D and the footprint EasyEDA_Cloud:QFN-20_L3.0-W3.0-P0.40-BL-EP1.7, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH390D?
QFN-20(3x3), with 21 pins. Its footprint is drawn on this page.
Where is the CH390D datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH390D?
JLCPCB lists it as part C41380359, with 4,399 in stock; the sellers' links on this page open their listings.
What can replace the CH390D?
Parts like it in the library: the CH641X by WCH (Nanjing Qinheng Microelectronics). Check their datasheets: a part that fits the footprint may still differ in its ratings.
