Description: The ESP8266 wifi module is a self contained so within integrated TCP/IP Protocol stack that can give any microcontroller access to your wifi network. The esp8266 is capable of either hosting an application or offloading all wi-fi networking functions from another application processor. Each Esp8266 Module Comes Pre-Programmed with an at Command Set Firmware, Meaning, You Can Simply Hook This Up to Your Arduino Device and Get About As a Wifi-Enhance as a Wifi Shield Offers (and That x) ! The esp8266 Module is an extremely cost effective board with a huge, and ever growning, community.this module has a powerful enough on-board processing and storage capability that allows it Ation 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, Including the Front-end module, is designed to occupy minimal PCB Area. The esp8266 supports APSD for Voip Applications and Bluetooth Co-Existance Interfaces, It Contains A self-Calibrated RF allowing it to work underl work. Ountain of Information Available for the ESP8266, All of which has been proved by amazing community support. In the documents Section Below you will find many Resources to Aid in using the ESP8266, Even Instructions on How to Transforming This Module Into an IoT (Internet of Things) Solution! Shifting and Will Require an External Logic Level Converter. Please do not power it directly from your 5V Dev board.This New Version of the ESP8266 WiFi Module has increased the Flash Disk Size from 512K to 1MBFEATURES: 802.11 B/G/NWI-Fi Direct (P2P), Soft tegrated tcp/ip Protocol Stackintegrated Tr Switch, Balun, Lna, Power Amplifier and Matching Networkintegrated Plls, Regulators, DCXO and POWER Management Units+19.5DBM Output Power in 802.11b Modepower Down Leakage Curent.
