Does ESP32-C3F support external SPIRAM ? (eg the standard QIO RAM like S2) ?
thanks, DF

Using pico-v3-02 MCU. Installed DEV ESP32 Support into Arduino. When compiling without -DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue resulting code is bootig and executing. Debug/Display code shows no use/existance of PSRAM as expected. Enabling RAM during compilation (-dboard_has_psram as above) ...

From ESP32S2 TRM i understand that external SRAM can be powered with 1.8V (or 3.3V; def) independant of voltage supply of internal Flash. I couldn't find that information for Pico-D4.
I read that internal Flash is powered 3.3V - can external SRAM be powered with 1.8V ?

thx TJ
