If we consider an IoT application containing memory intensive stacks such as Wi-Fi ,Mqtt and so on to be developed on module like esp wroom02D or esp8266DevKitC , what are the options available as fas as the memory is concerned?

I see that SPI is used for the memory interface in esp-Wroom-02D

Please suggest

Thanks

If you need more ram, your should switch to ESP32's
