Magic 8X8 RGB LED Matrix Colorduino Kit

Description:

The Colorduino is a RGB LED matrix driver platform based on ATMega 328P. This is designed to make it easy for a user to modify or write the firmware of Colorduino by Arduino IDE.

The driver circuit based on 3 MBI5168 constant current sink drivers and a M54564 darlington source driver, the Colorduino pairs the M54564 with a single DM163 constant current driver. In order to better drive the RGB matrix and reach its best performance, we use the professional LED driver chip DM163 on board, by using the DM163, the Colorduino gains three 8+6-bit channels of hardware PWM control of the LED’s freeing up the ATMega328P from having to implement it in software. And the DM163 comprises shift registers, data latches, 8×3 channel constant current and 64 x 256 gray level PWM for per color! Each channel provide a maximum current of 60 mA. So, each RGB dot has 256×256x256 = 16,777,216 colors (16 million) in theory, and it’s easy to use the 6 bit correction register to calibrate the current error for each color LED.

Power is supplied either by pin headers or via 2 sets of mini screw terminals, a slide switch selecting between the two. With the herder side, you can use the 5V power supply, and the terminal side now supports 6.2-7.5V power supply. More than 7V will cause the DM163 to overheat and more than 9V supply may burn your board.

Pins brought out the edge of the board include RX, TX and DTS, which can be used to reprogram the on-board ATmega chip, and SCA and SCL for I2C communication. A green LED on the front of the board indicates power, although it is mostly obscured as soon as you plug the matrix panel in.

The full Color 8X8 Matrix RGB LED is based on 64 Red, 64 Green, and 64 Blue individual LEDs. You can show full color pictures or characters with it. Easily controlled by your Arduino board and other Microcontroller boards.
