ESP32-S2 Schematic Symbol Mismatch – Only One VDDA in KiCad Lib?

[reig4s]

Hi all,

I was reviewing the ESP32-S2 schematic checklist from Espressif’s official documentation and noticed something odd.

In the checklist and reference schematics, it seems like multiple VDDA pins are mentioned. But when I look at the official ESP32-S2 KiCad symbol from Espressif’s library, there’s only one VDDA pin shown.

Here are the screenshots for reference:

Thats from the library,

And thats from the official documentation.
(i cant give the screenshot because im a new user)

Is this a known issue?
Should I manually edit the KiCad symbol to add the missing VDDA pins for proper layout and decoupling? Or are those internally connected and it’s safe to just connect the one?

Thanks in advance!

I don’t know where you got the first symbol from but the one in the KiCad standard library has stacked pins.

There are in fact three VDDA pins and two VDDP3 pins. They are stacked together in the symbol so they appear as a single pin in the schematic, but if you connect something to such a pin you will notice on your PCB that it’s connected to all of them.
