TM1638 Display / buttons board 4x4

TM1638 Display / led / buttons board - This board is not Retro but can be used in retro emulations. With 16 buttons and 8 seven segment displays, it is a nice I/O board that can be connected to the Arduino with only three connections. A nice ready-made solution if you want to do Retro emulation on an Arduino type board.
