Just follow SD design guideline in OEM DG. https://developer.nvidia.com/embedded/jetson-xavier-nx-product-design-guide

Hi sir,
I read the document and checking NX SD card interface is fixed at 1.8VIO.
Can you confirm it the SD card voltage is for only 1.8V?
It can’t read the 3.3V card?

thanks.

Hi, the pins are CMOS-1.8V/3.3V.

Hi Sir,
Thanks your confirmation.
thanks.
