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!
The onboard ESP8266 framework allows you to connect to most 2.4GHz WiFi networks (open or password protected). The Blynk Board input/ouput (I/O) pins can either control motors or LEDs, or read in values from light & position sensors. Each of the pins are located on the edge of the board and interface with alligator clip cables – a staple interface cable for beginner and advanced electrical engineer alike. Multi-colored LEDs indicate all sorts of status modes including how to identify which board is yours.
