Built to seamlessly bridge software and hardware, the Blynk Board and app offer the most efficient way to link a smartphone to a microcontroller – simply turn it on, connect, and build a project.

The Power of Blynk

Monitor local weather conditions, control LEDs from your phone, even send a tweet when it’s time to water your plants! Blynk is an easy-to-use app builder that allows users to add buttons, sliders, graphs, and RGB controllers to their phone. The SparkFun Blynk Board is specially designed to work with the ‘widgets’ within the Blynk mobile app to create IoT projects. Every Blynk Board comes fully programmed and also includes a Blynk subscription code card (15k Energy at a $10 value). You’ll be controlling the Blynk Board from half way around the world in no time.
