SparkFun Blynk Board - ESP8266 (WRL-13794)

The SparkFun Blynk Board is specially designed to work with the Blynk mobile app, for iOS or Android devices. Combining the Blynk Board with the Blynk app, you'll be able to easily complete a variety of Internet-of-Things (IoT) based projects: control LEDs from your phone! Wire up a door switch and receive phone notifications when it opens or closes. Plug a soil moisture sensor into a plant, and have it tweet at you when it's thirsty!

BotaniTweet Project

All of these projects - and more! - are pre-loaded into the Blynk Board. All you have to do is provision it (using the Blynk app), and start tinkering!
