    Just need only five connectors to arduino PCB (+5,-,DATA,CLK,STROB). Only 3 pin busy. Many examples of code at internet. not available, really. Large size is not even drawback Library code TM1638 in public domain http://code.google.com/p/tm1638-library/ Large bright two-color 8 LEDs (RED/GREEN/NONE) with dot. enought buttons. Good arduino display for ... Read more

    Very cheap and easy to use. The main library for it is available and well-known on the Internet, but requires a bit of skill to get working. 7-segment display was very bright. This could be considered a pro in some cases though. Also, the cable connected on the front of the board, which could make mounting it difficult. My board came with extra PCB ... Read more

    Easy to use, very tolerant to errors and is simple to implement. Arduino library is very easy to understand (and even create), can use basically any 3pins (for one module). And that is very handy. Never could use it for anything else than prototyping, since the connector is higher than the buttons could always be cheaper, even so, is essential and I ... Read more

    So many input output over a i2c connection. Can even be daisy chained, but each board need its own select. For more info on the used chip and how to use with arduino, check this out: https://code.google.com/p/tm1638-library/wiki/Reference Anyhow, this is an excellent item. Impossible to build your own for given price. Mine 2 blocks of 7 segmet displays ... Read more

    Easy to use, works great. I connected it to my Arduino Mega AT1280 and it works as expected. Buttons, LEDs and digital display work. I don't see any except that I forget to buy some cables/wires to connect to my arduino board. Since I'm getting back into playing with electronics, I didn't have any cables and I forgot to buy some. So for those like me,... Read more

    Product is built well and strong, based on the TM1638 chip, there is a free downloadable library to work with: http://code.google.com/p/tm1638-library/wiki/DefaultConstrutor Compared to what you pay you get a lot, because it contains a keyboard, display, LED, and more expansion option, it costs you only 3 pins of Ardoaino! Because everything works in ... Read more

    Can be used as simple keyboard and 7-seg LED monitor. Theoretically it is possible to extend the module to 24-keys keyboard by soldering 16 other keys to existing 8 keys. On the card are activated only 8 keys from 24. Also standard Arduino library supports only these these 8 existing keys. The datasheet can be found at site http://www.titanmec.com/doce/... Read more

    This board can be driven with only 3 pins from Arduino. It is a perfect choice if you want a large and cheap display for any use (clock, scrolling display, ...). Switches and double colors LEDs can be used easily. Ok, it's hugly, but it's work pretty well ! I would prefer a board less bigger, with pins on the other side. Board is shipped with a link ...

    Article relatively easy to use, long as you have some help. It has many uses. It has everything I need to make a traffic light and a tachometer for scalextric. Its price is very good, when compared with all the separate components, plus save a lot of work programming the micro If you find a counter, is its design. The connectors protrude from the screen ...

    Got it, wired it, uploaded example "sketch" to my Arduino Mega, and boom: Worked flawlessly. Displays are red, LEDs are red-green (green glows less than red when using 3.3V, remember this), buttons are very responsive. A perfect I/O gadget, as uses only 3 wires (Clock, Data and Select) for debugging bigger sets. Once debugged, you can take ... Read more
