✍ 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.

✍ 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

On-board ESP8266, a low-cost WiFi-MCU Module integrated and easy to prototyping development board. The best platform for IOT application development at the lowest cost.

The Development board based on ESP8266, integrates GPIO, PWM, IIC, 1-Wire and ADC all in one board. Power your development in the fastest way combining with NodeMCU Firmware!
