This chip key display module features a combination of eight 7-segment displays, eight red LEDs, and eight push-buttons. Making it ideally suited for making simple user interfaces.
All of the LEDs and buttons are driven and/or read by a TM1638 LED controller IC. This driver chip uses a simple 3-wire serial interface to communicate with your Arduino® compatible board.
