SD Card Initialization Help

Using Arduino Storage
20

Sorry, my english is poor.....So..
I understand you now.
But what is OP?

I looked at the schematic for the arduino board the OP is using and it appears that it has a level translator built in so the signals should be 3.3V.

Now I have two solutions if I didn't understand wrong.

  1. Select 3.3v MISO levels for the board if possible. Thus,I can get the CS,SCK,MISO,MOSI signals with 3.3V from the board.
  2. Change the SD card with a level translator IC.Thus, I can convert the CS,SCK,MISO,MOSI signals from the board to 3.3V.

Am I right?Thanks a lot!
