Introduction
City night is always beautiful. She is just like a charming girl, showing her beauty every time. The colorful light is jewelry, dotted on her dress. This is a 64x64 RGB LED Matrix Panel, it has 4096 full-color RGB LEDs in all. Each LED can be independently addressed and controlled. It requires at least 13 digital GPIOs to control the LED matrix. So the UNO board won’t be a good choice in this application, recommended Mega 2560, Raspberry Pi and the other kinds of microcontroller with large RAM and high speed. The led matrix has 2 IDC connectors (DATA_IN, DATA_OUT) on the back, you can cascade multiple panels and make a huge screen together. BUT Arduino doesn’t support this function, its speed is not enough to multiple panel. What's more, it is a high brightness, long life, no pollution, pure color LED display module. It can be used both indoor and outdoor, safety and stability, the module can not be mutually extrusion deformation, also can be used normally in harsh environment.
Note: This panel needs a 5V@5A power supply.
