+For example, this 64x8 RGB LED matrix from Amazon: [[https://www.amazon.com/gp/product/B088BTXHRG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1|BTF-LIGHTING WS2812B ECO RGB Alloy Wires 5050SMD Individual Addressable 8X32 256 Pixels LED Matrix Flexible FPCB Full Color Works with K-1000C,SP107E,etc Controllers Image Video Text Display DC5V]].
+The `WS2811` and `WS2812` are common in various LED strips. There are multiple libraries that allow you to control each LED.

+Each LED consumes about 20ma per color, so 60mA at full brightness. For a 256 pixel strip, that is 15,360mA.
