https://devzone.nordicsemi.com/f/nordic-q-a/67838/problem-with-nrf52840-usbHi there, To put a little bit of context, I&#39;ve designed a wearable that is now going towards pre-production (only some minors fix left to do). In the last iteration, we swapped the nRF52832 module for the nRF52840 for memory issues and to remove theen-USTelligent Community 13Mon, 02 Nov 2020 10:52:43 GMThttps://devzone.nordicsemi.com/thread/278025?ContentTypeID=1Mon, 02 Nov 2020 10:52:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1de2fddd-6f2d-416b-8d9a-5d25f2cdee28Kenneth<p>The USB peripheral have it&#39;s own internal power domain that require VBUS to be powered, so unfortunately there is no way to get USB working without VBUS connected no.
