Questions

Is there a KiCad symbol and footprint for the SL2.1A?

Yes. The symbol is EasyEDA_Cloud:SL2.1A_C6798314 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 SL2.1A?

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

Where is the SL2.1A datasheet?

CoreChips publishes it: the Datasheet link on this page opens it.

Where can I order the SL2.1A?

JLCPCB lists it as part C6798314, with 7,543 in stock; the sellers' links on this page open their listings.

What can replace the SL2.1A?

Parts like it in the library: the CH340C by WCH (Nanjing Qinheng Microelectronics), the CH340G by WCH (Nanjing Qinheng Microelectronics), the CH340B by WCH (Nanjing Qinheng Microelectronics) and the CH343G by WCH (Nanjing Qinheng Microelectronics). Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SL2.1A?

53 boards in 45 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
