I ordered 5 of these things (at 7.99, now it is lower, wish I waited) and received them at the back end of the upgraded date range I expected to get them in. The price of the shipping upgrade was very reasonable also. It looked like BangGood was going to miss the deadline but they got them to me in 9 days. WELL DONE! All the units powered up and performed as expected. They are clean, production run, and what I wanted.
The problem? BangGood's packaging. It's just plain awful! Wrapped in what looks like a garbage bag, and inside, the units were wrapped in a big piece of anti-static wrap. One unit actually fell out and was free-floating in the garbage-like bag. They were individually packaged, as expected, set in a cut piece of anti-static material, but, the device was pushed so far into the material that the pins actually came out the individual packaging and were exposed!
Customer service was not very good but they were prompt with personal replies. The issue I had with them is it took a few days to ship, so if you upgrade to the 6-9 day option, expect it in 9 days and forget about getting it early. Still, they did what they said they would do and that’s good enough for me.
I have seen these on eBay for much higher. Banggood has a lot of neat gear and at great prices. Maybe that is why their packaging is so bad. I would have liked my items in an anti-static envelope or a box at least.
I will buy from them again though. Thank you!

This is really nicely built board. Besides built in WiFI, great thing is that ESP8266 is really popular, so there are lot of tutorials and libraries for it. If you need more power or bluetooth connectivity you might consider getting ESP32 board: http://bit.ly/2x3Teik

Thereare many interesting documents about this NodeMcu module. I cannot paste URLs here but I recommend reading nodemcu.readthedocs.io ("en" folder contains the English version) and ***** (you can choose the English version clicking on the icon on the top-right).

Q:
Is there a link to how to use this?
Ive tried connecting via terminal emulator, and arduino IDE, and I cant seem to connect to it, Im probably doing something wrong, and It might help if there were some basic instructions.

Es arbeitet mit der Arduino IDE. Stelle sicher, dass du im Board Manager den ESP8266 nachinstalliert (online sind viele Anleitungen dazu erhältlich). Wenn die IDE sich danach immer noch nicht mit dem ESP verbindet musst du auf deinem Rechner noch den passenden USB Treiber (CH340) installieren. Ohne den Treiber findet dein Rechner den ESP nicht.
It works with the Arduino IDE. Make sure that you have installed the ESP8266 in the Board Manager (there are many guides available online). If the IDE still does not connect to the ESP afterwards, you need to install the appropriate USB driver (CH340) on your computer. Without the driver, your computer will not find the ESP.

Q:
Is development on this board similar to that of an Arduino? How is the development interface? The plan is to use the board with arduino starter kit sensors and relay data wirelessly to a PI or something, Will this suit my purposes?

Hifriend. ESP8266 and ESP32 work with 3v to 3.6v as datasheet said. This module (NodeMCU) has an internal regulator, só you can apply until 10v to VIN pin with no problem. Pay attention to all others pins work only with 3.3v, except A0 that work with 1.8v.

If you want to know the description of the chip, you may be able to search for "ESP-12F". If it is the pin of the development board, there is an associated mark on the board.If there are other usage issues, you can consult in the relevant professional forum.
