    @eduardov1:The LoLin board (which has the same form factor as those Amica v0.9 NodeMCUs... which means it's not very breadboard friendly (I use a pair of mini breadboards and space the MCU between the two)) but I digress) has the CH340G USB-to-UART Bridge chip which requires its own driver with WinXP, Win7, and early versions of Win8 (as well as Mac OS-X Yosemite and El Capitan , and perhaps some early distributions of Linux.) Here is a link:http://kig.re/2014/12/31/how-to-use-arduino-nano-m... to a website that discusses this problem fow the inexpensive Chinese versions of the Arduino Nano which uses the same CH340G chip and the drivers you download from there should work for the LoLin NodeMCU V3.

Here is an image of how I connect up a LoLin NodeMCU V3 using two mini breadboards. Seems there is like a 1.5cm gap between the two mini breadboards.-WRM

    Also, there seems to be three major providers of NodeMCU boards: Amica, DoIt, and LoLin. Each has boards which use the CH340G and both Amica and DoIt has switched to the Silicon Labs CP2101 (not sure why, the CH340G always works well for me. I have them on my several Arduino Nanos, WeMos D1 WiFi boards and LoLin NodeMCU boards. [Note: There appear to be a few other USB-to-UART bridge chip manufacturers, but on Node MCUs I have only seen the CP2102s and the CH340Gs. However, if you work with those AI-Thinker (or similar) ESP-xx WiFi modules, then you may decide to buy a general purpose TTL UART to USB adapter and I have seen versions of this kind of module board which use two other vendor's chips as well.

These other two USB-to-UART bridge chips are the FTDI F232R and the Taiwanese Prolific Technologies PL2303, so I suppose you may need to download drivers for either of these should you happen to buy one for use with say an ESP-01 or ESP-12E module.]
