    ESP8266 BASIC


    Main Disadvantage is of ESP8266 BASIC?

        512k modules will not support all features of ESP8266 BASIC.
        To make it fit on an ESP-01 and alike the following features have been removed for 512k modu

    Features

        Browser Based debugger
        Vars page
        TFT display functions
        OLED display commands
        LCD display commands
