The VU pin is directly connected to the USB port power pin which can deliver 5V if the board is powered using a USB. Because the operation voltage is 3.3V, there this a build-in voltage regulator that provide a stable 3.3V for the ESP8266 and the corresponding pins. This is for Linux only and specifically on Ubuntu 18.04 x84-64. The version 2 fits on a standard breadboard so that you can access any pin but because version 3 is wider, it also fits on a breadboard, but you cannot access the pins. Why is it "Gaudeamus igitur, *iuvenes dum* sumus!" In case you want to drive motors or servos or power LEDs, it's even better to use separate power supplies for them. This pin resets the board when pulled low. Technically the maximum input voltage is 15V but because at 15V the voltage regulator is producing a lot of heat and would break after a short time, it is recommended to supply an input voltage between 4.8V (USB input voltage is 5V) and 12V. The NodeMCU Lua Lolin V3 Module is a development board based on the ESP8266 ESP-12F Wi-Fi microcontroller. This may work on other ESP8266 based boards as well.
