Questions

Is there a KiCad symbol and footprint for the CH347T?

Yes. The symbol is EasyEDA_Cloud:CH347T and the footprint Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH347T?

TSSOP-20, with 20 pins. Its footprint is drawn on this page.

Where is the CH347T datasheet?

WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.

Where can I order the CH347T?

JLCPCB lists it as part C5122332, with 1,030 in stock; the sellers' links on this page open their listings.

What can replace the CH347T?

Parts like it in the library: the CH552T by WCH (Nanjing Qinheng Microelectronics) and the XPD767DP45 by Shenzhen Fuman Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the CH347T?

8 boards in 8 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
