Node MCU ESP8266 ESp-12 CP2102 WIFI development Board Module

The NodeMcu is an open-source firmware and development kit that helps you to
Prototype your IOT product within a few Lua script lines.

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

Lowest cost WI-FI
Less than $2 WI-FI MCU ESP8266 integrated and esay to prototyping development kit.
We provide the best platform for IOT application development at the lowest cost.
