Please consider WiFi Serial Transceiver Module w/ ESP8266 as alternative product

This version of WiFi Serial Transceiver Module is discontinued, please consider the latest version: WiFi Serial Transceiver Module w& ESP8266 – 1M Flash. There is not much change from the old version, just improved the Flash to be 1M and changed the color to be black, which is much cooler than blue.

We release a tutorial for ESP8266.

This is WiFi serial transceiver module, based on ESP8266 SoC.

The SOC has Integrated TCP/IP protocol stack

We have a set of documents in Chinese. We are preparing tutorials and demo software to showcase utility of this module.

Please buy this module only when you understand the existing documents.

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.
