https://devzone.nordicsemi.com/f/nordic-q-a/18449/nrf52---ok-to-leave-swdio-and-swdclk-unconnectedIf I use a breakaway for some debug pads which SWDIO and SWDCLK are connected to and then snap it off so the traces are no longer connected to anything, will this cause a problem? I&#39;d rather not use up space with resistors for pulling them either wayen-USTelligent Community 13Tue, 09 Jul 2019 17:01:03 GMThttps://devzone.nordicsemi.com/thread/197461?ContentTypeID=1Tue, 09 Jul 2019 17:01:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5999e3f2-dad0-4e1f-a6de-3dce5c324695Sami<p>Very helpful, thank you!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/71194?ContentTypeID=1Fri, 16 Dec 2016 22:22:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ea2ec277-9bb8-4216-8015-784c3b1e285aCharlie Skilbeck<p>awesome, I should have seen that, thanks.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/71193?ContentTypeID=1Fri, 16 Dec 2016 17:22:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:07b5b49b-c3a4-40ef-91f2-f94089ff79c0Sigurd<p>Hi,</p> <p>It&#39;s OK to leave them unconnected on the nRF52. You don&#39;t need any external resistors. As described <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/dif.html?cp=2_2_0_15_0#dap">here</a>, the SWDIO line has an internal pull-up resistor, and the SWDCLK line has an internal pull-down resistor.</p> <p><strong>Note:</strong> On the nRF51 it’s recommend to have an additional 1k ohm external resistor on SWDCLK.</p><div style="clear:both;"></div>
