Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month
Cheap, not worth building a display yourself. Can extend it with key pads by using the solder pads on the back up to two 12 key phone like pads could be used.
The headers need to be right angle types so the board can be flush mounted also the buttons need to be longer or extensions made available so they come to the same height or more as the displays for panel mounting.
A header or provision for it to connect to the other key-scan functions of the TM1638. I have written code to use these here at http://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewtopic&t=10889 its free to use and works with the free version of Bascom
Another great product from dx.com that costs less than the parts
