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.

Thanks, but
it's difficult for me. ))

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

Sorry for my english. I am using a translator.
Many programmers require the use of an additional adapter board to program
devices at 1.8V
This adapter board and covers 8 pin serial programming 1.8V devices. It is
very inexpensive to purchase.

I think it should work in conjunction with the Open Programmer 3.3V adapter
board.
