There is an associated, free, app necessary to control the LED sign. The QR code to download it is displayed on the included pamphlet. All easy and straightforward to use.
The sign is powered via a USB-A cord. No power block was included.
The app was easy to use and set-up and operation took me all of 15 seconds.
It is bright, beautiful, high-tech, and easy to use. Great quality item that I plan to use for parties.
