https://devzone.nordicsemi.com/f/nordic-q-a/54931/nrf52840-current-measurementHi all. I want to measure current consumption on nRF52840 DK (PCA10056). I have the SB40 cut and the 12 Ohm resistor placed in R90. I measure the voltage on this resistor. The problem is, that measured voltage refers only to the nRF chip, but I wanten-USTelligent Community 13Wed, 27 Nov 2019 12:17:21 GMThttps://devzone.nordicsemi.com/thread/222337?ContentTypeID=1Wed, 27 Nov 2019 12:17:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ba13511c-277a-4285-92b6-0879026b1f95Andreas<p>Hi,</p> <p>&nbsp;</p> <p>There is no similarly easy way to measure the current across the LEDs. See the <a href="https://www.nordicsemi.com/Software-and-tools/Development-Kits/nRF52840-DK/Download#infotabs">HW files</a>, you need to either measure the voltage across the resitors or e.g short SB9 using a resistor and disable U4.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
