- ESP8266 is a highly integrated chip designed for the needs of a new connected world. Its high degree of on-chip integration allows for minimal external circuitry， and its designed to occupy minimal PCB area.
- NodeMCU is an open source IOT platform. It uses the Lua scripting language. It is based on the eLua project， and built on the ESP8266 SDK 0.9.5.
- It uses many open source projects， such as lua-cjson，and spiffs. It includes firmware which runs on the ESP8266 Wi-Fi SoC， and hardwarewhich is based on the ESP-12 module.
- It uses CP2102 as UART bridge， and can flash firmware automatically by using nodemcu-flasher. It support apple's MAC OS.
- It is an integrated unit with all available resources on board. It is super simple to complement your existing Arduino projects or any development board that has I/O pins available.
