ESP8266 Nodemcu Lua WeMos D1 R3 simple models WiFi Arduinoo UNO board

AT commands: With serial transmission, AT commands issued directly operate more common in Arduino like as the main core, through Rx Tx control ESP8266 then extended wireless Internet capability.
NodeMCU: using LUA language development, and directly to programs in programmed ESP8266 memory, such a benefit is not completely plug-like Arduino 8051 and so this kind of single wafer.
Arduino IDE: the original raw SDK again because the core is the C / C ++, but repackaged and offers a variety of API so that the original will written by Arduino people can painlessly move to rewrite ESP8266 support Arduino IDE environment, the same as in writing Arduino. the same program is written directly to memory, and do not need to plug other single wafer.
Web SDK WF8266R.js: Taiwan Communications WF8266R built a powerful event system and so on a variety RESTfUL MQTT and WebSocket interface in ESP8266 inside, and for the sensing element and packaged application market a lot of WEB objects purpose is to allow beginners. or designer does not need a strong background apps and hardware will be able to do some interactive work.
Smart.js: Ireland Cesanta Software development, the javascript engine built ESP8266, the direct use of the page will execute js passed ESP8266.
