Questions

Is there a KiCad symbol and footprint for the ST3232B?

Yes. The symbol is st3232:ST3232 and the footprint Package_SO:TSSOP-16_4.4x5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ST3232B?

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

Where is the ST3232B datasheet?

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

Where can I order the ST3232B?

JLCPCB lists it as part C118284, with 7,454 in stock; the sellers' links on this page open their listings.

What can replace the ST3232B?

Parts like it in the library: the SP3232EEY-L/TR by MaxLinear, the MAX3232IPW by Texas Instruments, the MAX3232EIPW by Texas Instruments and the MAX3232ECPW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ST3232B?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
