This Arduino-compatible module uses three TI TLC5940 PWM LED chips to drive a 4x4 array of RGB LEDs. Each color is controlled by a different chip so you can adjust the reference resistors for the appropriate current. The TLC5940 chips are not directly connected to any Arduino pins, but a header is provided for you to make a manual connection depending on the needs of your sketch. Up to 16 of these modules can be serially connected to make a fantastic LED wall or a LED circle. It can be directly connected with Arduino via F/M cables. If you want ,you can also connect it to Interface shield through an IDC2x5 cables,and then plug the Interface shield to Arduino. NOTE: This is a Un-assembled Kit, you need soldering skill to assemble it. A tutorial is available as a reference. If you feel the assignment of the leds is not good enough, you could assign the LEDs in a custom pattern by wiring to the LED driving holes.
