LED Display (8 Digit) and KEYs (8 Bit) serial HID with TM1638 IC.

This Module comes with 8 tactile push buttons, 8 LED, and 8 Digit 7-Segment Display. With the serial driver IC TM1638, it only takes 3 I/O ports on the microcontroller (Arduino, STM, etc.) to set the Display and to read the Buttons.

Code examples and resources are available online.
