ESP8266 ESP-12E Serial WiFi Wireless Transceiver SMD Module with ADC, SPI and Ex

ESP-12E ESP8266 Serial Port WIFI Wireless Transceiver Module For Arduino 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.

The ESP8266 WiFi Module is a self contained SOC with 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. This module comes with AT commands firmware which allows you to get functionality like Arduino wifi shield, however you can load different firmware’s to make your own application on the modules’ memory and processor. Its a very economic module and has a huge and growing community support.

This module has onboard 80Mhz low power 32 bit processor which can be used for custom firmware’s. This also means that you can host small webpages without any external controller. For more details see : NODEMCU . The ESP8266 supports APSD for VoIP applications and Bluetooth co-existence interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.

ESP8266 is transforming the world with its low cost and high features which makes it an ideal module for Internet Of Things (IOT). It can be used in any application where you need to connect a device to your local network or internet. This module ESP-12 has 7 GPIOs.

Note: The ESP8266 Module is compatible only with 3.3V logic level and will not work directly with 5V devices (for both serial and GPIO access). You need a 3.3V compatible device or you will need to convert the levels before you use it.
