Features:

• The NodeMcu is an open-source firmware and development kit that helps you to prototype your IOT product within a few Lua script lines.The Development Kit based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board. Power your developement in the fastest way combinating with NodeMCU Firmware.
• Open-source, Interactive, Programmable, Low cost, Simple, Smart, Wi-Fi enabled. Code like arduino, but interactively in Lua script. Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware.
