ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution,allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry,and the entire solution,including front-end module,is designed to occupy minimal PCB area.
ESP-12F
ESP8266-12F is an enhanced version of ESP8266-12,perfect peripheral circuit,four-layer board technology,enhanced impedance matching,better signal output,whether it is stability or anti-jamming capability,PCB antenna through professional laboratory testing,ROHS certification ,Have been greatly improved! For those who choose ESP-12 before,even if the product has been made it does not matter,enhanced version is fully compatible with the firmware before the pin in the ESP-12 on the basis of the addition of six IO port,SPI port leads,the development more convenient, More extensive!

Warnings:
1.This module requires a 3.3 volt supply for VCC,and 3.3V logic.
2.It is not 5V tolant,Connect RX or TX on 5V FOR Arduino will destroy this module.
3.You must use a logic level converter,or a 3.3V FOR Arduino
4.The 3.3V supply on the FOR Arduino Uno has inadequate current capabilit to power this module.
5.You must provide a separate,higher 3.3V supply(about 300mA or better)
