Hello,
My system is going to run off a Lithium Ion battery.
I don't need to use the USB Interface on nRF52840.
Is it okay for me to leave VBUS, D+, D- floating?
And connect 4.2V Li+ Battery to VDDH?
Thanks,
Hani Abidi

As far and I know, there is no requirement to connect VBUS, D+, D-.
VDDH can accept upto 5.5V, so yes you can run with a li-ion battery with way.
