Please confirm treatment of VBUS on the nRF52840 if VDDH is usedhttps://devzone.nordicsemi.com/f/nordic-q-a/84395/please-confirm-treatment-of-vbus-on-the-nrf52840-if-vddh-is-usedWe are supplying the nRF52840 from 5 V into the VDDH pin. We are not using the USB interface, so I want to confirm what our options are for the VBUS pin. Can we leave it floating, or must it be grounded or have a capacitor on it?

Grounding the VBUS pin is recommended when not using the USB interface, the USB regulator decoupling, DECUSB, can be floating when not used.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Bendik</p><div style="clear:both;"></div>
