ESP12E ESP8266 Wireless Transceiver Module

The ESP12E ESP8266 is a highly integrated chip designed for the needs of a new connected world. This esp module offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or offload all Wi-Fi networking functions from another application processor.

It is completely addressable over SPI and UART protocols allowing you to connect your sensors or project directly to it through its GPIOs. ESP8266 is a low-cost Wi-Fi chip with a full TCP/IP stack and MCU (Micro Controller Unit) capability.

ESP8266 Serial Wifi Wireless Transceiver Module is a self-contained SOC with an integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. ESP8266 Serial Wifi Wireless Transceiver Module is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.

The ESP8266 has powerful onboard 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 the front-end module, is designed to occupy a minimal PCB area.

        1. Is the ESP12E and ESP8266 the same? 

        • The ESP12 is an RF module containing the ESP8266 SoC and other necessary components, like the antenna. It's a lot easier to design products with WiFi capabilities with a module like this because you can simply add the module without needing a lot of extra components. 

        2. What is the use of the ESP8266 WiFi module? 

        • The ESP8266 WiFi Module is a self-contained SOC with an integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 can either host an application or offloading all Wi-Fi networking functions to a separate application processor. 

        3. Can ESP8266 connect to Internet? 

        • The ESP8266 can be controlled from your local Wi-Fi network or the internet (after port forwarding). The GPIO pins on the ESP-01 module can be programmed to turn an LED or a relay ON/OFF through the internet. The module can be programmed using an Arduino/USB-to-TTL converter through the serial pins (RX, TX).
