Clarify NodeMCU ESP8266 VIN pin (#340)

Browse Source 
``VIN``: This pin can be used to use an external power supply with the board. Supply a voltage from
  3.3V to 12V to this pin and the linear voltage regulator on the board will power the board.

changed for more clarity to:

``VIN``: This board can be powered by an external power supply by using this pin. Supply a voltage between
  3.3V to 12V to this pin and the linear voltage regulator on the board will power the board.
