https://devzone.nordicsemi.com/f/nordic-q-a/47254/problem-with-power-supply-on-nrf52840-dkHello, I have some problems when running the development kit. It seems the problem might be somewhere on the PCB, something related to power sources and power distribution across the development kit. I have programmed simple ble_app_uart program intoen-USTelligent Community 13Tue, 18 Jun 2019 08:48:25 GMThttps://devzone.nordicsemi.com/thread/193336?ContentTypeID=1Tue, 18 Jun 2019 08:48:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:786706c2-4a40-4df2-96d5-5ce05da2a59dkosarj<p>I have not solved it. I needed it to measure power consumption. So I just assumed that the power consumption will be good and moved to next development stage. We bought around 5 nRF52840-DONGLE boards and I flashed my code to it and tested the power consumption there. The dongles are cheap and have everything that is needed to run any code on nRF52840 SoC. So I can&#39;t suggest them enought if you have problems with the development kit. It is good to keep the development kit for programming and debugging, but the dongle can be programmed even without it with its default bootloader.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/193285?ContentTypeID=1Tue, 18 Jun 2019 04:29:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:441bfe8a-f931-46c6-aee5-f46a27a69612hzhuxin<p>I have the same issue with you, i need to know how to solve the problem!</p> <p>You solve it?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/187165?ContentTypeID=1Wed, 15 May 2019 09:03:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0fc949a0-dd6f-465e-a91a-7563f3c32ff0kosarj<p>Yea, you don&#39;t&nbsp; even need to bother anymore. The board is going further to *** every day. The power supply ICs are heating up fast, power supply keeps resetting 5 times per second and I hate all of it. *** this.</p><div style="clear:both;"></div>
