How Many K1000C I need

If it is single-point single-control, there are a total of 6000 pixels (100X60=6000). WS2812 is a SPI LED strip. Each port of K-1000C can support 2048 pixels for SPI LED strip, and 512 pixels for DMX LED strip. Then a total of 6000/2048=3 is needed. So a total of 3 K-1000C LED controllers are needed. You have to read the specification first to see how many pixels the controller port supports. K-1000C LED controller specifications can be found here.
