Powering Up the Blynk Board
Once you've gathered all of the materials from above, it's time to power up the Blynk Board! Grab your USB Cable, plug one end into a computer or USB wall adapter, and plug the other into the Blynk Board.

You should immediately see the small, red "PWR" LED illuminate, followed shortly thereafter by a random-looking blinking of the large, RGB LED.
