An overview of the pin assignments for the nRF5340 can be found on<a href="https://infocenter.nordicsemi.com/topic/struct_nrf53/struct/nrf5340.html"> the Infocenter</a> at nRF5340 Product Specification/Hardware and layout/Pin assignments.<br />The pins differ based on which package variant you have (aQFN94(TM) or WLCSP95).</p> <p>A devicetree (.dts- and .dtsi-files) configuring SPI for the nRF5340-DK is found withing NCS at&nbsp; &lt;ncs-installation&gt;/zephyr/boards/arm/nrf5340dk_nrf5340.</p> <p>If you need more guidance, please tell me which NCS version you are using.</p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>
