5 V tolerant Arduino Zero compatible board
We know the reason why newly coming Arduino Zero has "gray terminal", meaning it is NOT 5 V tolerant but 3.3 V logic, where we cannot connect conventional 5 V logic devices. Now I made a quick solution. As you see, this board has full-3.3V-5V logic level converter in each terminal. Now we can enjoy all of conventional Arduino shield in ARM based Arduino!!
