Hi everyone, I'm trying to figure out if it's safe to power an xbee off
the 3.3V header on the bbb ( P9_3 / P9_4 ) .. I need 250ma-300ma MAX
is this safe and stable? It would seem like it, but I want to confirm..
thank you!

finally, add the rootfs. anyway, that's the approach i prefer, and
it seems to work as students like to be able to build *and test*
something fairly quickly, rather than just doing a massive amount of
work, and wondering if it will work in the end.
