    Board is quality builded. All components are soldered tight and PCB is very strong.

    Package comes with mounting screws.

    TM1638 chip requires only 3 pins from micro-controller to be driven.


    Cable count be a little bit longer.

    Buttons are noisy.

    8-level brightness adjustment works, but steps of brightness are not proportional equal.


    Works great.

    Using it with Arduino Uno. With TM1638 library it is very simple to program all functions.

    Good thing is what it could be joined in sequence of 6, so in future you could expand display in your needs.


    Great board for experiments and final DIY project.
