I have nRF9151dk board with on-board SD Card connector. I used this ticket as reference: nRF9160DK onboard SD-card connector.

The VDD connected to micro sd card connector have as voltage 1.8V and the majority of sd cards works with 3.3V. I can not use sd card in this connector, but if I use level shifter with conversion to 3.3V, sd card works. Is it possible to use this connector with other voltage? What is the utility of this sd card connector as the majority of sd cards works with 3.3V?

Regards,
GoncaloS

Hello again,

For example this one should be pin compatible:

While it is not available for new designs, there is still lots in stock for example on DigiKey if you just need them for the nRF9160 DK:
