Clarify NodeMCU ESP8266 VIN pin (#340) 

``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.

- ``A0``: This pin can be used as a normal GPIO pin (like ``D1`` etc) but additionally can measure
voltages from 0 to 1.0V using the :doc:`/components/sensor/adc`.

3.3V to 12V to this pin and the linear voltage regulator on the board will power the board.
- ``ENABLE``/``RESET``: When these pins are triggered, the board resets. The difference between the pins
is how they can handle voltages above 3.3V.
