ESP32 Forum

Hi,
just a short question.
Is there any possibility to connect an external PSRAM to you ESP32-S2-MINI module.
If necessary, together with a SPI flash.

Not sure but there doesn't seem to be any efuse to change spi pins at boot so if it would be possible you would have to boot from internal flash then change spi pins in software using gpio matrix. There may be issues or limitations when trying to run flash and psram through matrix.
