Questions
Is there a KiCad symbol and footprint for the CH446X?
Yes. The symbol is EasyEDA_Cloud:CH446X and the footprint Package_QFP:LQFP-44_10x10mm_P0.8mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH446X?
LQFP-44(10x10), with 44 pins. Its footprint is drawn on this page.
Where is the CH446X datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH446X?
JLCPCB lists it as part C3018882, with 15 in stock; the sellers' links on this page open their listings.
What can replace the CH446X?
Parts like it in the library: the CH446Q by WCH (Nanjing Qinheng Microelectronics), the MT8816AF1 by Microchip Technology, the SGM6516YLFB44G/TY by SG Micro and the MS8816P by Hangzhou Ruimeng Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the CH446X?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
