    A very interesting gadget for you Arduino hobby. With 8 digits, 8 bi-colour leds en 8 button it can be used for almost everything. And you only need 3 Arduino ports (and 2 voor GND en 5 V). A library for easy use can be found (http://code.google.com/p/tm1638-library/). And detailled information I... Read more

    - Once you find the libraries, everything falls into place easily. - The libraries are well written with plenty of examples to go off. - The display has adjustable brightness (through software). - Having both LED colours above the buttons makes the board more versatile in general with what you of...

Arduino library already exists. Coding is simple. Long term durability unknown; time will tell. Buttons not aligned with of... Read more

    Very simple to use with Arduino. The library is easy to implement and simplifies use to enable rapid prototyping. Included spacers are a bit short, and the edges of the PCB are a little rough, you may want to sand down the edges. The placement of the IDC headers is odd, they should be on the or A... Read more

    - Very useful to get numeric and/or state output and to provide input to a sketch into an Arduino using only 3 pins. - Rather cheap for all the functionality provided. - The little ribbon cable used to chain several modules can be used to connect the Arduino, when soldering a adequate outlet on a...
