            The resulting UART setting will be xxx-8N1, where xxx represents
            the chosen bit rate.

            Enables auto-baud detection for the UART console.

            By typing a few characters into the console shortly after boot,
            NodeMCU can automatically detect your terminal settings and
            adjust accordingly.

            If you are doing advanced things with the console, you may want
            to disable this feature.

            It is recommended to leave this enabled - if it ever produces
            output, something has gone seriously wrong and you probably want
            to know about it.

    config NODEMCU_EMBED_LFS

        help
            The LFS (Lua Flash Store) normally has its own partition entry,
            and can can be replaced at will. Optionally, the LFS can instead
            be permanently embedded into the NodeMCU firmware image itself.
            This can be useful for scenarios where over-the-air firmware
            upgrades are needed to also bundle Lua code. The major downside
            is that once embedded, the LFS can no longer be changed, as
            doing so would break the firmware checksums and signatures and
            leave the system unable to boot.

            The default option is to not embed the LFS, in which case LFS is
            looked for in a partition of type 0xC2 and subtype 0x01.

            To embed LFS data into firmware, use:
              ./tools/embed_lfs.sh /path/to/file1.lua /path/to/file2.lua ...

        help
            Embedded LUA Flash Store size. Set to zero to use an LFS partition
            instead of embedding the LFS within the NodeMCU firmware itself.
