nRF9160-SiP SD-Card interface?

[Smart.Enrg]

Hi,

Is it possible to add SD card (either SPI or MMC mode) to nRF9160-SiP?

Hoping since the SiP is powered by Zephyr-OS, that should be possible.

Please advise. Thanks in advance, for your attention and any help.

The nRF9160 has no QSPI interface but you can use a SPI interface and connect CLK, CS, MOSI, MISO to CLK, D3, CMD, D0. 
D1 and D2 from the SDcard are not connected and should probably pulled-up.
Please note that you probably need at least 2.8V for power and IO.
