It is not yet available, they have decided to not use the GPIO pins directly, 
but to run things through an arduino nano, so it's a $20 option instead of a 
$100 option.

support for this is not yet in any release of the allstar software, but they 
were planning a release in December that was postponed due to a death in the 
community. They were planning to have this support either in that release or 
within a couple of weeks after.
