https://devzone.nordicsemi.com/f/nordic-q-a/57830/gpio-configuration-to-drive-ledDear All, I would like to know which is the better GPIO configuration to drive a LED for extremely low power consumption. We have a board with nRF52832 SoC with GPIO connected to a LED catode and LED anode connected through resistor to a voltage of poweren-USTelligent Community 13Fri, 14 Feb 2020 17:29:48 GMThttps://devzone.nordicsemi.com/thread/234490?ContentTypeID=1Fri, 14 Feb 2020 17:29:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d7215a7-1198-4d54-87fc-157a2dee9b86Dmitry<p>Hi,</p> <p>There&#39;s no difference. As you pointed out, cathode will be connected to VDD,&nbsp; there is no path to leak out. Also, you can configure pin as H0D1 (high drive low, disconnected high).</p><div style="clear:both;"></div>
