Soooooo, I got my new FEZ Panda II and I thought I might like it. I was right, I really do!
Basically, this Arduino sized board (compatible with some Arduino shields) is like the "FEZ Mini" on steroids! One of the many great things this board has is almost all the processor pins broken out to connectors that accept wires or shield pins. Other great items are a Micro-SD drive and a realtime clock. I did a firmware update without a problem. FEZ Mini programs are running just fine with an update to Panda II libraries.
