https://devzone.nordicsemi.com/f/nordic-q-a/73806/is-it-recommended-to-put-capacitance-on-the-nrst-pinIs it a good/bad idea to put capacitance on the nRST line. I noticed the nrf52840 DK does not have any capacitance on the nRST line. At least none that I can find, tracing that signal on the schematic is a bit tough. There is 100 pF on the 52840 dongleen-USTelligent Community 13Mon, 12 Apr 2021 12:28:12 GMThttps://devzone.nordicsemi.com/thread/304270?ContentTypeID=1Mon, 12 Apr 2021 12:28:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d9585305-20e9-445d-85ac-b3878bbf45cdketiljo<p>There are on-chip reset circuitry on the device including pull up, so external capacitor and resistor is not needed. But it doesn&#39;t harm to place the usual 10 kohm / 100 nF on the pin.&nbsp;</p> <p>The USB dongle has this to make the reset line a but more robust since the board doesn&#39;t have a housing.&nbsp;</p><div style="clear:both;"></div>
