Questions

Is there a KiCad symbol and footprint for the STPM34?

Yes. The symbol is EasyEDA_Cloud:STPM34TR and the footprint EasyEDA_Cloud:QFN-32_L5.0-W5.0-P0.50-TL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STPM34?

QFN-32-EP(5x5), with 33 pins. Its footprint is drawn on this page.

Where is the STPM34 datasheet?

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

Where can I order the STPM34?

JLCPCB lists it as part C129475, with 346 in stock; the sellers' links on this page open their listings.

What can replace the STPM34?

Parts like it in the library: the STPM32 by STMicroelectronics and the MCP3918A1-E/ML by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the STPM34?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
