Description: ESP8266 NodeMCU V2 Development Board with CP2102
Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware.
Code like arduino, but interactively in Lua script.
Event-driven API for network applicaitons, which faciliates developers writing code running on a 5mm*5mm sized MCU in Nodejs style.
Greatly speed up your IOT application developing process.
On-board ESP8266, a low-cost WiFi-MCU Module integrated and easy to prototyping development board. The best platform for IOT application development at the lowest cost.
The Development board based on ESP8266, integrates GPIO, PWM, IIC, 1-Wire and ADC all in one board. Power your development in the fastest way combining with NodeMCU Firmware!

You can find the firmware source code and documentation on Github, as well as nodemcu-flasher, a Windows only tools to flash the firmware to a module. There’s also a separate tool called esptool that will let you flash nodemcu from Linux. In case you find the documentation is all over the place, you might want to checkout NodeMCU video tutorial below.
