Hi.

There is a GPIO interfaces section in our documentation describing the GPIO interfaces of the nRF9160 DK.

Best regards,

Hello Bhargav,

I think Mathias sent you the wrong link: https://docs.nordicsemi.com/bundle/ug_nrf9160_dk/page/UG/nrf91_DK/hw_description/nrf9160_board_controller.html

There's a matrix here that shows the used pins from the nRF52840 towards the nRF91 on the kit. 

The HW files for the kits can be found here, there you'll also see the pins used on the nRF52840 and which ones are routed out to pin headers. https://nsscprodmedia.blob.core.windows.net/prod/software-and-other-downloads/dev-kits/nrf9160-dk/hardware-files/nrf9160-dk---hardware-files-1_1_0.zip

Best regards
