Features: Put on your sunglasses before wiring up this LED matrix - 64 eye-blistering RGB LEDs adorn the for a blast of configurable color. Arranged in an 8x8 matrix, each pixel is individually addressable. Only one micro-controller pin is required to control all the LEDs, and you get 24 bit color for each LED. Wiring it up is easy: there are two 3-pin connection port. Solder wires to the input port and provide 5VDC to the +5V and ground pins, then connect the DIN pin to your micro-controller. You'll also need to make a common ground from the 5V power supply to the micro-controller. Since each LED can draw as much as 60mA (that's up to 3.5 Amps per panel if all LEDs are on bright white) we suggest 5V 2A power supply. For most uses, you'll see about 1-2A of current per panel. Color of light can be changed through program.
