ESP8266은 TCP/IP 프로토콜 스택을 내장한 WIFI SOC(원칩 시스템)이므로, 어떤 MCU도 WIFI에 쉽게 접속할 수 있도록 합니다.
이 모듈은 UART 또는 SPI 시리얼통신으로  AT 명령어를 이용하여 동작하여 쉽게 MCU에 연결하여 IOT를 구현할 수 있습니다.

주의 : 이 모듈은 5V to 3V 컨버터가 내장되어 있지 않습니다. 절대 5V를 바로 연결하지 마십시요

ws ESP8266 improve the peripheral circuit, enhance the impedance matching, signal output is better, both stability and anti-interference ability, have been greatly improved.
ESP8266 is a ultra-low power UART-WiFi module. It has excellent dimensions and ULP technology compared to other similar modules. The module is special design for monile devices and Internet of Things (IoT). When devices connect to WiFi with ESP8266 module, it can process LAN communication.

ESP8266 shows in three options: onboard PCB antenna, IPEX connectors, half hole.

Esp8266 can be applied to Smart Grid, Intelligent Transportation System, Smart Home, handset and industrial control system etc.
