I am concerned whether I need to use a voltage divider to power my ESP8266 module. My concerns stem from the warnings that I have heard in multiple tutorials. Everyone seems to regard the ESP8266 as being very sensitive to supply voltage.
Has anyone use the ESP8266 with an supply voltage greater than 3.5 V? What were the effects? Is it even necessary to make a voltage divider?
I am asking because my application has limited real estate.
