The SparkFun ESP8266 WiFi Shield is an Arduino compatible shield for
the ESP8266 WiFi SoC - a leading platform for Internet of Things (IoT)
or WiFi-related projects. There are a variety of designs based around
the ESP8266, including tiny, modular boards and more accessible
development boards like our very own SparkFun ESP8266 Thing. The
ESP8266 WiFi Shield finds a middle ground between the Module and the
Thing that provides a great introduction to the ESP8266 - without
leaving the comfortable hardware confines of your Arduino. If you just
have an Arduino project that needs an inexpensive gateway to the
Internet, the ESP8266 WiFi Shield does everything from turning on an
LED to posting data with

The ESP8266 WiFi Shield comes pre-flashed with an AT-command firmware,
so it can be controlled by any UART, but it also breaks out and
provides command access to all of the ESP8266's I/O. Since this is an
Arduino shield, it makes it easy to attach to any development board
that utilizes the Arduino R3 layout. All it will take is a little
soldering to attach the necessary headers. The ESP8266 is much more
than a simple serial-to-WiFi gateway. It has almost a dozen I/O that
can be configured as digital inputs or outputs - it even has an ADC!
These GPIO are all broken out towards the top-left side of the shield.
Additionally, the ESP8266 WiFi Shield can be repurposed and
reprogrammed through the programming port found on the top-right side
of the shield. Whether you want to add AT commands of your own, or
flash custom firmware on the ESP8266, this port may come in very handy
especially with it utilizing the pinout of our FTDI Basic breakouts.

This shield comes populated with all components as shown in the images
and schematic; and at Play-Zone you also get a set of stackable
headers for free.
