Description: This is the SparkFun ESP8266 Thing Dev Board – a development board that has been solely design around the ESP8266, with an integrated FTDI USB-to-Serial chip. The ESP8266 is a cost-effective, and very capable WiFi-enabled microcontroller. Like any microcontroller, it can be programmed to blink LEDs, trigger relays, monitor sensors, or automate coffee makers, and with an integrated WiFi controller, the ESP8266 is a one-stop shop for almost any Internet-connected project. To top it all off, the ESP8266 is incredibly easy-to-use: firmware can be developed in Arduino, and uploaded over a simple, serial interface. The ESP8266 Thing Development Board breaks out all of the module’s pins, and the USB-to-serial converter means you don’t need any peripheral components to program the chip. Just plug in a USB cable, download the Arduino board definitions, and start IoT-ing.

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 phant.io, and can be programmed just like any microcontroller. You can even program the Thing through the Arduino IDE by installing the ESP8266 Arduino addon.

The ESP8266 Thing Development Board is a relatively simple board. The pins are broken out to two parallel, breadboard-compatible rows. The USB connector sits next to an optional power supply input, and an ON/OFF switch – controlling power to the ESP8266 – sits next to that. And 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. If your project requires a power source other than USB, the Thing Dev Board includes footprints for a 2-pin JST, 2-pin 3.5mm screw terminal, or a simple 0.1"-pitch 2-pin header. Unlike the original ESP8266 Thing, the ESP8266 Thing Dev Board does not have a built-in LiPo charger.

The Thing Dev Board even includes a PCB trace antenna as a default WiFi antenna, it’s cost-effective and actually works really well! If you need to connect a more sensitive antenna, or need to route outside an enclosure, a U.FL connector is also available on the board. Some soldering will be required to get the U.FL connector functioning but instructions can be found in the Hookup Guide we have written for the dev board.

Note: We’ve provided a few Example Sketches to experiment on your SparkFun ESP8266 Thing Development Board. These sketches can be found in the Hookup Guide in the Documents section below!
