ESP32 Forum

Hi,

I would like to confirm which pins of module "ESP32-S3-WROOM-2-N32R8V" work with 1.8 volt logic level.

Mainly "user pins".

For me, the 1.8 volt logic level is a problem, i need to know if all the pins are 3.3 volts.

Only GPIO47 and GPIO48 are 1.8V ?
From what i understand i can use these two io's, they are not connected in external 32MB flash memory.

Thank's.

From the datasheet:

As the VDD_SPI voltage of the ESP32-S3R8V chip has been set to 1.8 V, the working voltage for
GPIO47 and GPIO48 would also be 1.8 V, which is different from other GPIOs.

In other words, only GPIO47 and 48 are 1.8V, the rest is 3.3V. Those two GPIO pins may not be connected to the flash, but they're powered by the same voltage.

If GPIO47 and GPIO48 were used as input, what is their logic level ?

3,3V or 1,8V ?

Thank's.

1.8V.
