Hello,
I'd like to know if VP and VN could be use as normal pins when used as ADC1_0, ADC1_3, RTC, GPIO input only.
I ask this because from here viewtopic.php?t=3206 and from other topics I understand that something has changed about the use of S_VP and S_VN.
I only care about if they work as well as the other pins.

That is answered in the data sheet.

From page 15 and 56 of the datasheet I read that there is nothing strange on those pin, they are only input without pull-up/down.username wrote: ↑Sat Dec 24, 2022 12:41 amThat is answered in the data sheet.

I didn't read nothing more here, that's why I choose to write on this forum.
Can you confirm that they are "normal" pins?

What is your definition of a "normal" pin?Can you confirm that they are "normal" pins?
Re: VP and VN pins on ESP32-WROOM-32
I mean a pin that doesn't hide something, e.g. some kind of inefficiency

in the page 55, item 02 say:
input-only and no internal pullup/pull-downGPIO pins 34-39 are input-only. These pins do not feature an output driver or internal pullup/pull-down circuitry. The pin names are: SENSOR_VP (GPIO36), SENSOR_CAPP (GPIO37), SENSOR_CAPN (GPIO38), SENSOR_VN (GPIO39), VDET_1 (GPIO34), VDET_2 (GPIO35).
