The Latest ESP-12F ESP8266 Wifi Module AP & Station Remote Serial Wireless IoT Board is an integrated chip designed for the needs of a new connected world. ESP8266 is a low-cost Wi-Fi chip with a full TCP/IP stack and MCU capability. It can handle all the necessary overhead for communicating with your network, such as TCP/IP stack and communicating with your 802.11 networks.

ESP8266 Serial Wifi Wireless Transceiver Module has a powerful enough on-board processing and storage capability that allows 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.ESP8266 Serial Wifi Wireless Transceiver Module 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 much WiFi-ability as a WiFi Shield offers.

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. 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. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, which is designed to occupy minimal PCB area.
