8x8 LED Matrix on Development Board

I found this interesting LED matrix where all sorts of experiments can be done. Here is demo where i switch between the LEDs one by one. The operation of these is explained in the sites below.

The LED matrix used in the demo is Bi-color Matrix with Red and Green.
Pin-outs:
*Pin-outs may vary. Hence check all pins by toggling 3V (say, Button Cell) among all possible combinations.
*NEVER USE 5V directly to any LED or the LEDs will burn out. ALWAYS Use 5V in series with 680 Ohm or 1k Ohm.


The pins below are the ground pins and on the left are for Enable:
Red pins- Red LED anode
Black pins- Red LED cathode
Green pins- Green LED anode
Blue pins- Green LED cathode
