This is a roll of addressable (WS2812B) RGB LEDs. Each LED has a built-in controller chip which allows you to daisy-chain the LEDs and control them individually - all from a single GPIO!
Yes, absolutely. As long as each individual WS2812 chip has a connection for +5v, Ground, and Data In, it will work, and as long as the Data Out of one chip connects to another chip’s Data In, they will work in a chain of any length.
The biggest limitation is for very long strips - the high current needed to power large strips can result in significant voltage drop, to the point that they won’t work correctly near the end of a very long strip without additional connections along the power and ground rails.
