We are using ESP32-S3-WROOM-2-N32R8V which includes 8MB of octal spi in-package.

We would like to add more PSRAM off-package. We prefer to use the external single spi (MOSI IO11, MISO IO13, SCLK IO12, and chip select IO42) because we are short of pins.

Has anyone added external PSRAM to this chip ...
