Is there a KiCad symbol and footprint for the CH448U?
Yes. the footprint Package_SO:QSOP-24_3.9x8.7mm_P0.635mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH448U?
QSOP-24, with 24 pins. Its footprint is drawn on this page.
Where is the CH448U datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH448U?
JLCPCB lists it as part C42432808, with 3,270 in stock; the sellers' links on this page open their listings.
What can replace the CH448U?
