I finally got around to looking at 4 TinkerKit LCD Module I had purchased at a Ham Fest.
These LCD Modules are actually treated as an Arduino Leonardo.
The nice part is that these LCD Modules have two WIre/IWI connectors. I will try tomorrow with the master/slave wire examples.
Cannot use them with any Arduino shields.but they do have a purpose and many possible uses.
