Production Description: This is WiFi serial transceiver module, based on ESP8266 SoC with an integrated TCP/IP protocol stack It can either host the application or offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities allowing it to integrate with sensors and other devices through 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.
