Questions
Is there a KiCad symbol and footprint for the CH9329?
Yes. The symbol is EasyEDA_Cloud:CH9329 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH9329?
SOP-16, with 16 pins. Its footprint is drawn on this page.
Where is the CH9329 datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH9329?
JLCPCB lists it as part C2838834, with 349 in stock; the sellers' links on this page open their listings.
What can replace the CH9329?
Parts like it in the library: the CH340C by WCH (Nanjing Qinheng Microelectronics), the CH340G by WCH (Nanjing Qinheng Microelectronics), the SL2.1A by CoreChips and the CH340B by WCH (Nanjing Qinheng Microelectronics). Check their datasheets: a part that fits the footprint may still differ in its ratings.
