The ESP8266 reference for the NodeMCU is here:
http://esp8266.github.io/Arduino/versions/2.3.0-rc2/doc/boards.html#nodemcu-1-0
The pertinent info is:
If you do not wish to modify your A0 voltage divider on the NodeMCU, then you must work with the two SMT resistors on the board and calculate the A/D readings appropriately.

The pertinent info is:
The board also features a NCP1117 voltage regulator, a blue LED on GPIO16 and a 220k/100k Ohm voltage divider on the ADC input pin.
