The SparkFun ESP8266 Thing is a breakout and development board for the
ESP8266 WiFi SoC - a leading platform for Internet of Things (IoT) or
WiFi-related projects. The Thing is low-cost and easy to use, and
Arduino IDE integration can be achieved in just a few steps. We've
made the ESP8266 easy to use by breaking out all of the module's pins,
adding a LiPo charger, power supply, and all of the other supporting
circuitry it requires.

Why the name? We lovingly call it the "Thing" due to it being the
perfect foundation for your Internet of Things project. The Thing does
everything from turning on an LED to posting data with [1],
and can be programmed just like any microcontroller. You can even
program the Thing through the Arduino IDE by installing the ESP8266
Arduino addon [2].

The SparkFun ESP8266 Thing is a relatively simple board. The pins are
broken out to two parallel, breadboard-compatible rows. USB and LiPo
connectors at the top of the board provide power - controlled by the
nearby ON/OFF switch. LEDs towards the inside of the board indicate
power, charge, and status of the IC. The ESP8266's maximum voltage is
3.6V, so the Thing has an onboard 3.3V regulator to deliver a safe,
consistent voltage to the IC. That means the ESP8266's I/O pins also
run at 3.3V, you'll need to level shift any 5V signals running into
the IC. A 3.3V FTDI Basic is required to program the SparkFun ESP8266
Thing, but other serial converters with 3.3V I/O levels should work
just fine as well. The converter does need a DTR line in addition to
the RX and TX pins.
