Connecting SD CARD to STM32H743 without level translator

[Mosi]

Guys I just don't get this part in CubeMX. What does it mean by "voltage converter"? Does it refer to voltage translator? In that case why would a software stack cares about a voltage translator (which is basically a 1:1 interface) and changes the signals on pin completely by selecting different modes.

Hello @Mosi and welcome to the community!

The voltage converter refers to the voltage level conversion that takes place when interfacing with an SD card. It ensures that the signals sent by the host are compatible with the voltage requirement of the SD card.

I suggest you have a look at this Thread, it would be helpful.

Thank you.
