I feel like this was asked before but cannot seem to find it after a good session of searching on the forum. So, has anyone used some of the pre-made LED matrixes from places like SparkFun? Such as:
http://www.sparkfun.com/products/683
I realize that’s a 3-color version but the dimensions are at least somewhat close to what I ended up with when I made my own matrix (which was, itself, based upon the MB-6582 matrix)? The only downside is that it’s flat and 3 colors when I only need one. Also not exactly sure how to mount that since I do not see any screw-holes or anything.
What about the serial variants (such as http://www.sparkfun.com/products/759)? I would imagine that would need a customer driver of course.
I apologize if this has come up before. Feel free to flame if it has 
But thought I would ask and get impressions. I think I will still go with my own solution for consistency with the other parts of my control surface but thought I would check just the same.
