Questions

Is there a KiCad symbol and footprint for the STM32L031F4P3?

Yes. The symbol is MCU_ST_STM32L0:STM32L031F4Px and the footprint Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STM32L031F4P3?

TSSOP-20, with 20 pins. Its footprint is drawn on this page.

Where is the STM32L031F4P3 datasheet?

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

Where can I order the STM32L031F4P3?

JLCPCB lists it as part C5269756, with 0 in stock; the sellers' links on this page open their listings.

What can replace the STM32L031F4P3?

Parts like it in the library: the STC8H1K08-36I-TSSOP20 by STC Micro, the STM32F030F4P6 by STMicroelectronics, the PY32F003F18P6TR by PUYA and the CH32V003F4P6 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 STM32L031F4P3?

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