Are the on board pushbutton switches mapped to any of the GPIO? are they accessable via any of the headers?

Hello timgray,

as you can see in the schematics (at github) the pushbuttons are mapped over resistors to one pin on the a13. They are not mapped individually to the gpio´s.

The buttons are connected to analog input pin of the cpu. If you press a button the input voltage changes between 2V and 0V if I remember correctly. You can read this forum page:
