I am trying to copy the ESP32 DevKit USB behavior in my own PCB (my pcb project).
When the USB is plugged, ESP should be powered from USB. I will use this to program the board only
When the USB is not plugged, the ESP should be powered from the PSU. This is how the board will be used in normal operation
While studying the DevKit schematics (link), I see there is a green box and I am not sure why is that circuit marked:
Looking at the CP2102 datasheet (link), I think it is wiring it like in page 6 and 9:
Thank you!
Why does the ESP32 DevKit schematic has a green box?

Re: Why does the ESP32 DevKit schematic has a green box?
If I recall correctly, our PCB designers use green boxes like that to indicate what has changed in comparison with the previous version of the PCB/devkit. If you're simply trying to build one yourself, it is not really relevant.
