Flexible RGB LED strips usually only have a single row of LEDs. But Adafruit’s new Flexible NeoPixel RGB LED Matrix has 256 LEDs arranged in an 8×32 matrix. It has a thick and flexible PCB backing, so you can wrap it over bent or curved surfaces.
Despite the demo video below, the component isn’t meant to be bent repeatedly or at extreme angles. You can make a curved iBling with it though.
Bend your browser to Adafruit’s shop and order the Flexible 8×32 NeoPixel RGB LED Matrix for $140 (USD).
