Is there a KiCad symbol and footprint for the CH330N?
Yes. The symbol is Interface_USB:CH330N and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH330N?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the CH330N datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH330N?
JLCPCB lists it as part C108996, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CH330N?
Parts like it in the library: the MIC2012PCM-TR by Microchip Technology, the MIC2012YM by Microchip Technology, the MIC2012YM-TR by Microchip Technology and the MIC2012ZM by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the CH330N?
47 boards in 40 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
