This is a 32x16 RGB LED Matrix Panel, it has 512 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. 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@2A power supply. And if you connect 4 or more screen, it needs a high performance controller, such as Mega 2560, Raspberry. .etc.
