NodeMcu Esp8266 CP2102 WIFI Internet Of Things Development Board Based ESP8266 CP 2102 Wireless Module

The NodeMcu is an open-source firmware and development platform that helps you to prototype your IOT product with just a few lines of Lua script. The Arduino-like hardware IO with advanced API will dramatically reduce the redundant work for configuring and manipulating hardware. Basically you can code like Arduino, but interactively in Lua Script.
