The All new NodeMcu ESP8266 V3 Lua CH340 Wifi Dev. Board is a fast leading edge low-cost WiFi technology. Modern high-level mature LUA based technology. It is an integrated unit with all available resources on board. It is super simple to complement your existing Arduino projects or any development board that has I/O pins available.

Modern Internet development tools such as Node.js can take advantage the NodeMCU with the built-in API to put your idea on the fast track immediately. NodeMCU is built based on the mature ESP8266 technology to take advantage of the abundant resources available on the web.

NodeMCU has ESP-12 based serial WiFi integrated on board to provide GPIO, PWM, ADC, I2C and 1-WIRE resources at your fingertips, built-in USB-TTL serial with super reliable industrial strength CH340 for superior stability on all supported platforms. This module is one of the cheapest available wifi-modules in the market. V3 or Version3 is the latest version of this module. This tutorial, however, will facilitate you to connect all the versions of ESP8266 NodeMcu, i.e V1, V2 or V3.

1. 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.
2. Nodejs style network API Event-driven API for network applications, which facilitates developers writing code running on a 5mm5mm sized MCU in Nodejs style. Greatly speed up your IOT application developing process.
3. Development Kit The Development Kit based on ESP8266, integrates GPIO, PWM, IIC, 1-Wire and ADC all on one board. Power your development in the fastest way combination with NodeMCU Firmware!

The NodeMcu is an open-source firmware and development kit that helps you to prototype your IoT product with few Lua script lines. The Development Kit based on ESP8266, integrated GPIO, PWM, IIC, 1- Wire and ADC all in one board.
