Explore Embedded ESP8266 ESP01 Wifi Module  (Multicolor)

ESP8266 is not just a UART to Wifi Adapter. It is a SOC comprising of full TCP/IP Stack and host of GPIO pins. You can possibly use it in two ways: As a serial to wifi Adapter: In this mode the module can be connected to UART pins of the micrcontroller and can be used as any other wifi sheild. It works with Arduino and all other major micrcontrollers out there. Infact this is the way it was marketed. As a MCU and Wifi Sheild with Arduino: However, the community found out the way to access the GPIO pins of the SOC and use it bot as a MCU and a WiFi solution. Interestingly, the community added support for the module to work directly with the Arduino IDE. This way one can program the module itself with arduino style code. To do this, you will require a USB to Serial Convertor like the CP2102. This is WiFi serial transceiver module, based on ESP8266 SoC. This is the ESP-01 VariantThis has an integrated tcp/ip stack 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. The Module Comes with a default AT Firmware.
