The Adafruit NeoPixel NeoMatrix has 64 super bright LEDs in an 8 x 8 matrix. Each NeoPixel is 'split' with one half being RGB and the other is a white LED. This combined LED enables you to choose any colour or illuminate using with white light. Available in 3 colours of white light – warm white (3000K), neutral white (4500K) and warm white (6000K).

If you need more, then you can also daisy chain NeoMatrix together. For the second matrix, connect the DIN connection to the first panel DOUT. There is a single data line with a timing-specific protocol. Since the protocol is sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC or mbed.
