#53653 is there any point in removing LED from esp8266 12e? It is not constantly on.
I want to use deep sleep mode with batteries and i have wemos d1 mini board.
So i was thinking to remove this LED. Do I need to power the board with 3.3 through the pin or its fine through the microUSB?
In addition to get it work I heard I need to short some pins? Is that right?

Please any suggestions which will reduce power consumption on this D1 mini :)
