sparkfun 4x4 button pad and pcb

Other Hardware LEDs and Multiplexing
1

can someone please tell me if it is possible and how to connect this button pad (Button Pad 4x4 - Breakout PCB - COM-08033 - SparkFun Electronics) to arduino? i will use single colour led's and not rgb ones. can i connect to arduino without multiplexing? is there a ready made code to read buttons and light up the corresponding led when a button is pressed?

thank you

i wont be needing simultaneous pressing of more than one buttons if that makes a difference

Well 4x4 = 16. So sixteen inputs and sixteen outputs... Without multiplexing of some kind, only the Mega would have enough I/O.
