This is the Plug & Play NODEMCU Lua IoT ESP8266 Wifi Controller Board V3 (LATEST VERSION -- NO DRIVER DOWNLOAD IS REQUIRED). The NodeMcu is an open-source firmware and development kit that helps you to Prototype your IOT product within a few Lua script lines.

    Open-source
    Interactive
    Programmable
    Low cost
    Simple
    Smart
    WI-FI enabled

Features

Arduino-like hardware IO
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.
 
Nodejs style network API
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.
