https://devzone.nordicsemi.com/f/nordic-q-a/58201/nrf9160-doubtsHi I&#39;m reading the documentation and I have some doubts about the nRF9160 board. So, the board is divided into the micro controller nRF9160 SiP ( https://infocenter.nordicsemi.com/index.jsp?topic=%2Fstruct_nrf91%2Fstruct%2Fnrf9160.html&amp;cp=2_0 ) anden-USTelligent Community 13Mon, 24 Feb 2020 12:04:17 GMThttps://devzone.nordicsemi.com/thread/235937?ContentTypeID=1Mon, 24 Feb 2020 12:04:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:59a34f32-2e8b-4f00-98ff-5eaabea8a6a4Didrik Rokhaug<p>Hi.</p> <p>The nRF9160 consists of 1 SiP and nothing more.</p> <p>However, on the nRF91 DK, there is also an nRF52840 SoC that is used as a &quot;board controller&quot;. It controls a set of switches on the DK that routes pins from the nRF9160 to either the headers or other functions. You can see a full list of which pins are routed where here: <a href="https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/board_controller.html">https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/board_controller.html</a></p> <p>You can also use the nRF52840 to add Bluetooth functionality to your application.</p> <p>Best regards,</p> <p>Didrik</p><div style="clear:both;"></div>
