    * Nice clear display even at low brightness.
    * Display and buttons on one board and controller.
    * easy to control
    * daisy chaining of multiple boards!
    * TM1638 chip is easy to control


    * at full brightness there is a significant voltage drop over the cable.
    * bit hard to find the datasheet. Google is your friend and a good translated datasheet is available.
    * no schematics so figuring out what segment and button maps to where is a bit of a hassle but doable with some effort.
    * high IDC connector headers prevent easy integration with a frontpanel.
    * Low buttons make it hard to put it in a frontpanel.


    Low cost display that can be used in a lot in a lot of homebrew electronics projects. Beats the clarity of a 2*16 LCD display and has extra buttons.

    The daisychaining is a nice feature.


    Cheap, clear, easy to control. They can be used in many projects. So get a few, for this price its hard to make it as cheap as this.
