Blynk Board ESP8266 App Builder - SparkFun WRL-13794

The SparkFun Blynk Board is specially designed to work with the ‘widgets’ within the Blynk mobile app to create your next IoT project. Monitor local weather conditions, control LEDs from your phone, even send a tweet when it’s time to water your plants! Every Blynk Board comes fully programmed and also includes a Blynk subscription code card (15k Energy at a $10 value), which will be needed to connect the Blynk Board to your Blynk account, connect to a Wi-Fi signal and you are ready to start Blynking! You’ll be controlling the Blynk Board from halfway around the world in no time.
Blynk is an easy-to-use app builder that allows users to add a variety of buttons, sliders, graphical displays, and even RGB controllers to their phones.
Onboard every Blynk App Builder Board is the economic yet powerful ESP8266 framework that will allow you to connect to most 2.4GHz WiFi networks, that are either open (no password) or protected with WPA, WPA-2, or WEP authentication. This board interfaces with the outside world using input/output (I/O) “pins” that can either control real-world objects, like motors or LEDs or read in values from sensors (like light or position). Each of the Blynk Board’s pins is accessible via the large, metal-encircled holes on the edge of the board. These large holes are designed to interface with alligator clip cables – a staple interface cable for beginner and advanced electrical engineers alike. During setup, the RGB LED on the Blynk Board will be your window into its soul. The board uses this multi-colored LED to indicate all sorts of status modes including how to identify which board is yours.
Blynk is a digital dashboard for your iOS or Android device that allows you to easily build graphical interfaces by dragging and dropping widgets to control your newest IoT projects! With the Blynk app, you will be able to control the Blynk board or any other compatible hardware remotely by displaying sensor data, analyzing your surroundings, activating a function of your project, and much more.
