Happy to see that these powerful little things are getting more affordable. What does those expansion pins do? Can they be used for I/O like button and LED?

Just about every pin on this processor can be used for GPIO. Some pins, like the DDR interface, can only perform one function, but the vast majority can be configured to do one of seven different functions.
