Hi, not exactly a problem rather it is question on whether this setup is suited for what I want,
- I want 3.3V for the device and sensor systems, possibility of reducing it to another lower value using I2C.
- I want to control the nPM1300 without any Buttons, possibly putting nPM1300 in Hibernation mode/Reset using nRF5340 BLE?
- from the datasheet of nRF5340 page 769 ''When supplying power from a USB source only, VBUS must be connected to VDDH if USB is to be used.'' , but i will have battery as well, so in that case when USB is not there, VDDH is connected to VBUS, is that okay?
Here is the nRF5340 ( uBlox Nora ) section :
