Question on VDD and VSS internal connection

OLAMIDESET · ‎2026-03-19

Should each vdd pin of the stm32f407zgt6 read continuity like the blue pill on multimeter, are they internally connected within the chip or separated? Similary for all the vss pins are they also all connected vss inside stm32f407zgt6

Thanks

Your response is philosophical!

I understand the first paragraph bit the second paragraph is confusing. I will try and simply follow the datasheet and Application note.

Yes I will but can you please provide a screenshot of the vdd pins that read continuity and vss pins that beep continuity on free stm32f407zgt6 chip? Thanks

Sorry I cannot do that. I don't have that MCU part number.

The previous answer is generic and applies to all STM32 and the test I did is done on another MCU part number.

Thank you for your understanding.

That's always the best way!

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

In what way(s) ?
