Serial WiFi module based on SoC ESP.  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. ESP based ESP-12E module has powerful on-board processing and enhanced storage capabilities (~4MB flash) 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. You will need minimal external circuitry for the module and the entire solution. The module comes with default AT command firmware installed and you can program it to run C code as well as Lua code by upgrading the firmware with another.
