Can you describe what (if any) LEDs are lighting up on your end. Also, please confirm that the following switches on the DK are in the correct positions:</p> <ul> <li>Power switch in the ON position.</li> <li>nRF power source in the VDD (middle) position</li> <li>VEXT-&gt;nRF in the OFF position</li> <li>FLOW CONTROL in the ON position</li> <li>nRF ONLY | DEFAULT in the DEFAULT position</li> <li>TRACE in the Def. position</li> </ul> <p>You can also follow the <a href="https://docs.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/intro.html">nR52840 DK user guide</a> for reference if you&#39;re having issues.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
