ESP8266 Datasheet

ESP8266 PINOUT ESP8266 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.

When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements.

Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface.

    Large number of Lua programs for standalone ESP8266 are appearing these days but for all of them the SSID and password are firmware coded.Therefore while one moves away from the tested network it does not work. I have seen only one ,very lengthy that provides the entry of SSID & password to be written in a webpage first while ESP is in own access mode and thereafter it goes to wifi mode so that one can use it any network.A simple Lua program with above features to switch on and off GPIO0 is required.

Looking for the latest from TI?
