However, the latest batch exhibited abnormally high power consumption. During software debugging, an anomaly was detected on the GPIO14 pin : en-USTelligent Community 13Tue, 19 Aug 2025 15:15:44 GMThttps://devzone.nordicsemi.com/thread/546086?ContentTypeID=1Tue, 19 Aug 2025 15:15:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9cf7b6eb-db29-4223-82ad-1ba8a1ed1619Kenneth<p>Hi,</p> <p>My recommendations is to check the PIN_CNF[] register:<br /><a href="https://docs.nordicsemi.com/bundle/ps_nrf52805/page/gpio.html#register.PIN_CNF-0-31">https://docs.nordicsemi.com/bundle/ps_nrf52805/page/gpio.html#register.PIN_CNF-0-31</a></p> <p>If the INPUT field is Connect, then the pin must be connected physically to a defined logic level (e.g. it can be connected to gnd, vdd, pull-up, pull-down or otherwise have some external circuitry that ensure the pin is in a low (&lt;0.3*VDD) or high state (&gt;0.7*VDD)).</p> <p>If the INPUT field is Disconnect, then it doesn&#39;t matter if the pin is connected to a logic level or not.</p> <p>Let me know if I should transfer this case to Nordic QA for failure analysis.</p> <p>Kenneth</p><div style="clear:both;"></div>
