NodeMcu Wi-fi IOT Wireless Module for Arduino Projects

NodeMcu Wi-fi IOT Wireless Module for Arduino Projects Perfect for all your Arduino Internet Of Things projects

This NodeMcu is a tiny Wi-Fi wireless board, based on ESP8266. It integates GPIO, PWM, IIC, 1-Wire and ADC all in one board.

Perfect for all your Arduino Internet Of Things projects.

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. Specification:- USB-TTL included, plug&play
