Questions

Is there a KiCad symbol and footprint for the CH552G?

Yes. The symbol is EasyEDA_Cloud:CH554G 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 CH552G?

SOP-16, with 16 pins. Its footprint is drawn on this page.

Where is the CH552G datasheet?

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

Where can I order the CH552G?

JLCPCB lists it as part C111292, with 7,143 in stock; the sellers' links on this page open their listings.

What can replace the CH552G?

Parts like it in the library: the STC15W408AS-35I-SOP16 by STC, the STC8G1K08-38I-SOP16 by STC Micro, the PY32F002AW15S6TU by PUYA and the PY32F002BW15S6TR by PUYA. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the CH552G?

58 boards in 49 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
