Is there a KiCad symbol and footprint for the CH571K?
Yes. The symbol is EasyEDA_Cloud:CH571K_C5440339 and the footprint EasyEDA_Cloud:ESSOP-10_L4.9-W3.9-P1.00-LS6.0-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH571K?
ESSOP-10, with 11 pins. Its footprint is drawn on this page.
Where is the CH571K datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH571K?
JLCPCB lists it as part C5440339, with 213 in stock; the sellers' links on this page open their listings.
What can replace the CH571K?
Parts like it in the library: the PY32F002AA15M6TU by PUYA. Check their datasheets: a part that fits the footprint may still differ in its ratings.
