I try out a lot of boards for my projects. Many do not make it into a project just because they may not have features I am looking for at the time. I also am addicted to microcontrollers so I have a lot of extra stock of various ones that I have tried. This is one of those. It works and was never embed in a permanent project. Now I need to make room for more. Here is your chance to pick up this board at a nice discount and help me fund future projects. :)
