f) ESP-pSRAM32 can be driven from 1.8V do 3.3V and need not to drive 1.8V and can be driven with 3.3V right? will check this on Monday... ivan VDD is 1.8V h) if we combine ESP32-D2WD with ESP-pSRAM32 we must use 1.8V cause intern Flash and ESP-pSRAM32 share Dataline PINS I'm not sure whether this i...
