Questions

Is there a KiCad symbol and footprint for the CH561Q?

Yes. The symbol is EasyEDA_Cloud:CH561Q and the footprint EasyEDA_Cloud:LQFP-64_L10.0-W10.0-P0.50-LS12.0-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH561Q?

LQFP-64M(10x10), with 64 pins. Its footprint is drawn on this page.

Where is the CH561Q datasheet?

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

Where can I order the CH561Q?

JLCPCB lists it as part C87388, with 0 in stock; the sellers' links on this page open their listings.

What can replace the CH561Q?

Parts like it in the library: the CH32V103R8T6 by WCH (Nanjing Qinheng Microelectronics), the CH32V203RBT6 by WCH (Nanjing Qinheng Microelectronics), the CH32V208RBT6 by WCH (Nanjing Qinheng Microelectronics) and the CH32F103R8T6 by WCH (Nanjing Qinheng Microelectronics). Check their datasheets: a part that fits the footprint may still differ in its ratings.
