Full Color 8x8 LED RGB Matrix Driver for Arduino (Colorduino) 

This is a RGB matrix driver built around the ATMEGA328P microcontroller chip. This driver was specifically designed to drive RGB LEDs meaning you won’t have to connect any additional hardware. All you have to do is upload Arduino software to the ATMEGA (look for Colorduino libraries) by connecting the driver using an FT232 USB adapter (UART). Connect your RGB matrix, and admire the display. The extruding pins also allow for I2C communication making cascading a possibility. As for an alternative programming interface, you have the option to program the board through ISP headers as well. 

You may also choose how to power your system thanks to an on-board switch (choose between power from headers or screw terminals). For headers the driver supports 5VDC and, for the terminals, it can support up to 7VDC (make sure not to exceed this limit to avoid burnt chips). The integrated DM163 current driver allows for up to 3x 8+6-bit channels making this driver compatible with 60mmx60mm 8x8 RGB matrices (square and circle dot).
