NodeMCU is an open-source development board and firmware based on the widely used ESP8266 -12E WiFi module. It allows you to program the ESP8266 WiFi module with the simple and powerful LUA programming language or Arduino IDE. With just a few lines of code you can establish a WiFi connection and define input/output pins according to your needs exactly like Arduino, turning your ESP8266 into a web server and a lot more. It is the WiFi equivalent of ethernet module.
Now you have Internet of things (IoT) real tool. With its USB-TTL (CP2102 Chip) , the nodeMCU Dev board supports directly flashing from USB port. It combines features of WIFI access point and station + microcontroller. These features make the NodeMCU an extremely powerful tool for Wifi networking. It can be used as an access point and/or station, host a web server, or connect to internet to fetch or upload data.
