DFR0460 64x32 RGB LED Matrix Panel (4mm pitch)
US$85.75
This is a 64x32 RGB LED Matrix Panel, it has 2048 full-color RGB LEDs in all. Each LED can be independently controlled. To control this LED Matrix, at least 13 digital GPIOs are required. 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. You are highly recommended to use microcontrolloers with large RAM and high speed to control this LED, such as Raspberry Pi, Mega 2560. Please note that the Arduino do not support all functions as its speed is not enough to run multiple panels.
