    Hello.
    Is 1.8V SPI programming possible?

    You would need a level shifter

    If I replace LD1086v33 with LD1086v18 in SPI Flash@3.3, will it work?

    Or should I make another such adapter. 3.3V to 1.8V

    Replacing the voltage regulator is part of the modifications needed.
    While 3.3V IO is still compatible with 5V IO, 1.8V is not.
    Therefore you also need a real level shifter on data lines.

    Is it possible to use such a level shifter?
    For which data lines can this be used? Which lines are input/output?

    Sorry for my english. I am using a translator.
