NodeMCU is an open source robot brain with a super fast clock, built in WIFI, and tons of room to fit your code. Perfect for building IoT projects and robots that communicate with their friends. You can use Arduino IDE to write and upload code, so none of your favorite habits have to change.
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!
