I would like to power the module with an external voltage ensuring that everything works correctly. From the website I read that an external 3V3 regulator is foreseen even if you want to power the WIFI correctly. In order to power the module with only the USB-C connection or with a separate power supply, it would be enough to connect the 3V3 regulator with:
- input to the VBUS terminal
- output on pin 3V3
- clearly its ground to GND
In this way can I power the module both with the USB-C cable and with a voltage of 5V applied on the correct VBUS terminal? better not at the same time clearly.
I then read on the diagram that without connecting the lipo battery there would be a flashing LED … is this correct? how do i turn it off if so?
