Well how am I suppose to know that from the package? It seems to imply that it works with all arduino on the package quote “ardunio compatible” us the first feature on the list. It doesn’t seem to suggest any particular arduino doesn’t work. What ardunios does it work with are there any others I should not buy to not waste money? The Uno works but what else? In addition I’m using the TFT 2.8" touch screen (which version I don’t know because there appears to be no marking indicating which) are there any ardunios that are compatible with both of the shields? Because what you guys seem to be saying there is no ardunio that is compatible with both of the two shields. How am I suppose to know this before I buy this? How am I suppose to know that I need to check a wikipedia page before buying this?
