https://devzone.nordicsemi.com/f/nordic-q-a/121574/using-ppk-to-measure-the-power-of-nrf54l15-dk-made-it-brokenHi I have one nordic nRF54L15 DK using as peripheral, I want to know the power of it. Thus, I use PPK2 to be a 1.8 voltage source and connect VOUT to P6 pin 1 and GND to P6 pin 1 as the diagram shows: At first it works well, but when I increaseen-USTelligent Community 13Tue, 20 May 2025 11:03:23 GMThttps://devzone.nordicsemi.com/thread/536173?ContentTypeID=1Tue, 20 May 2025 11:03:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f1c799a2-ef33-4e2c-92fe-ed5da66d20abPaKa<p>Yes, with the voltage on the DK same as supplied from the nRF-PPK2 then you are OK. That will be the same as using the amperemeter mode so not sure what advantage it will give you though.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/536093?ContentTypeID=1Tue, 20 May 2025 07:02:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9b0c017e-1c80-4968-ac19-59db066dccd2Ziyao Zhou<p>Thank you for your information, if I use the power profiler to be a voltage source on the P3, using the same with the DK 1.8V, is it acceptable to measure the power?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/535944?ContentTypeID=1Mon, 19 May 2025 10:17:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6fb76e86-b598-4a23-a8f8-ada52373d72cPaKa<p>The maximum voltage for the nRF54L15 is 3.6V so applying 3.7V is outside the maximum ratings and may damage the board.</p> <p>The VDD setting on the DK should be the same as applied to the nRF54L15, if there is a big difference then you may see issues with UART/Programming only or worst case, you may damage the Debugger on the board and thus break it.</p> <p>Attach the jumper agian and see if the board works, if so you should be good as long as you ensure to keep the voltages as stated above. If not then you may have broken the debugger and that would mean you&#39;ll need to get a new board.</p><div style="clear:both;"></div>
