Specifications:
Size: Approx. 5.7x3x1cm/ 2.24x1.18x0.39"
Advantage:
1. Open-source
2. Interactive
3. Programmable
4. Low cost
5. Simple
6. Smart
Wi-Fi enabled

Code compatible , but interactively in Lua script.
Nodejs style network API
Event-driven API for network applications, which facilitates developers writing code running on a 5mm*5mm sized MCU in Nodejs style.
Greatly speed up your IOT application developing process.
Lowest cost WI-FI
It is a tiny board, based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board
Package Included:
1/3/5/10/20 x NodeMcu Lua CH340G ESP8266 WIFI Internet Module (optional)
Fantastic quality board for a fantastic price. I already had the CH340 USB driver installed for a different board so the NodeMCU worked right away with Arduino IDE. There are 3 main ways to use this:
- Program it using Lua, I believe the firmware it comes with supports this although I didn't try it.
- Write code for it in Arduino IDE (C++). This is the most flexible and highest-performance option, and gives you access to extensive libraries available in Arduino IDE with one button click. Environment is very similar to coding for Arduino.
- Use it as a "dumb" WiFi peripheral with AT commands sent over the serial port from another CPU (Hayes modem style). The firmware you need to load for this is fairly easily found on the web.
Note that it's wider than some other NodeMCU boards so it doesn't leave any connection points available beside it when on a standard project board, but this is easily solved using some non-stranded hookup wire connected underneath.

Q:
Hello, is this NodeMcu ESP8266 ESP-12F or ESP-12E?
olá, está placa é o NodeMcu ESP8266 ESP-12F ou ESP-12E ?
Arduino ide doesn't automatically have this board. You have to add it.
You need to open Arduino IDE, choose File-->Preferences and then add this URL: ***** into the section that says: Additional Boards Manager (urls), save or OK, Then you have to go to Tools--> Boards Manager and add 8266 to the list of boards.
If you are not sure, try this step by step tutorial at *****

Q:
Are the data pins 3.3v or 5v tolerant? Clearly the board accepts 5v, and there is a voltage regulator to drop the supplied voltage to 3.3v - my understanding is that the ESP8266 is only 3.3v tolerant - so if you supply 5v to VIN do the data pins only provide 3.3v? Can you interface 5v I2C modules to this device, or only 3.3v I2C modules?

Is this module compatible with the Geekcreit UNO R3 ?

I cannot boot nodemcu from Vin with voltage of 5 volts. The dev board only boot from USB. Can you please tell me how to power the unit without using the usb?

Wasn't able to edit my previous question so here is the modified question:This is not the same as previous V3. Pin Rows are wider: 1.1in vs 0.9in and there was a LED on the board connected to D0 that doesn't seem to exist. The ESP8266 Wifi chip seems to run warmer than the previous V3 but is much cooler than the super hot V4. The builtin LED seems to be controlled by GPIO 02 (D4) and not GPIO 16 (D0). It has Ver 0.1 marked on the board near D0. If this is really a V3 devkit, how many different versions are available?

You have to enter the ssid and password to your WiFi in your code. The device will then connect to the network you specified. Look at example code to see how it's done
