https://devzone.nordicsemi.com/f/nordic-q-a/84859/nrf52840-vbus-current-leakageHi, I have some problem with NRF52840. When I use software example &quot;ram_retention&quot; in peripheral directory on 2 diff&#233;rents board I have 2 differents state of VBUS pin. I have made &quot;Erase chip&quot; before programming the 2 boards.

The VBUS is a pure input, and there is no leakage current/voltage out of VBUS pin.</p> <p>Kenneth</p><div style="clear:both;"></div>
