The LED5 doesn&#39;t light up, ony the LED1 lights up with a weak flickering light.en-USTelligent Community 13Mon, 22 Jun 2026 10:43:37 GMThttps://devzone.nordicsemi.com/thread/568247?ContentTypeID=1Mon, 22 Jun 2026 10:43:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7b756808-0811-475f-b38f-1cea97fa3c77IsabelPalacios<p>Hi Samruddhi,</p> <p>Thank you very much for your reply.</p> <p>Yes, I have tried with a different USB cable, USB port and computer, and the jumper is put on between&nbsp;<span>&nbsp;VDD_NRF and VDD_5V (P22).

Have you tried using a different USB cable, USB port, and computer? Can you also confirm that the jumper is put on between VDD_NRF and VDD_5V (P22)? If you have already tried this, can you please share a picture of your setup so that I can look more in detail on this?</p> <p>Best Regards,</p> <p>Samruddhi</p><div style="clear:both;"></div>
