The MOD-WIFI-ESP8266-DEV from Olimex is a development board with the famous ESP8266EX WIFI IC onboard.

This module comes with 2MB (16Mb) of SPI flash memory and all GPIO resources are available for breadboarding once the pin headers have been soldered (included). The I2C and SPI interfaces are also available.

It's easy to implement the module in your existing designs - the castellated pads and flat underside allow you to solder it directly on other PCBs. The module can be used for home automation, smart plugs/lights, mesh networks, industrial wireless control, baby monitors, IP cameras, sensor networks, wearable electronics and more.

This module is recommended for people that already have some experience with ESP8266.
