VUSB connection to GND, if USB will not be usedhttps://devzone.nordicsemi.com/f/nordic-q-a/69598/vusb-connection-to-gnd-if-usb-will-not-be-usedHi! Looking at the schematics for the nRF52833 reference circuitry I see that when USB is used, the VBUS is connected to the C18 capacitor, then GND, and if USB isn&#39;t used, the VBUS and DECUSB are connected directly to GND. We&#39;re not sure if ween-USTelligent Community 13Fri, 18 Dec 2020 19:45:39 GMTRE: VUSB connection to GND, if USB will not be usedhttps://devzone.nordicsemi.com/thread/285913?ContentTypeID=1Fri, 18 Dec 2020 19:45:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9f84ebd7-bf11-44bf-ac9d-a691728ecbffMarjeris Romero<p>If you don&#39;t plan to connect C19 to DECUSB then I recommend don&#39;t connecting C18 to VBUS, since if you plan on using USB you will need to have both C19 and C18.</p> <p>If you are unsure I recommend you follow the reference circuit for USB. Have the footprint for both C19 and C18, and if you find out you are not using USB you can use a 0 ohms resistor instead of C18 and desolder C19.</p> <p>Best regards,</p> <p>Marjeris</p><div style="clear:both;"></div>
