Questions
Is there a KiCad symbol and footprint for the STPM33?
Yes. The symbol is EasyEDA_Cloud:STPM33TR and the footprint EasyEDA_Cloud:QFN-32_L5.0-W5.0-P0.50-TL-EP3.5-A, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the STPM33?
QFN-32-EP(5x5), with 33 pins. Its footprint is drawn on this page.
Where is the STPM33 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STPM33?
JLCPCB lists it as part C222411, with 71 in stock; the sellers' links on this page open their listings.
What can replace the STPM33?
Parts like it in the library: the STPM34 by STMicroelectronics, 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 STPM33?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
