Seems like the same add on sensors work with other boards.  The newer
boards if anything have more IO.

Heh, well even the Arduino is moving to arm, the arduino Due is a 32 bit
cortex M3, and most of the UAV folks seem to think that's too little too
late.  At least the ardu pilot/copter folks are advocating skipping the
Due and porting to the m4f.

I've not seen anything that cheap with enough sensors/control to do a
UAV.  Something like this one:

$180 no GPS, $200 mediatek gps, $250 uBlox GPS.

Looks pretty similar to:

Once you add the nice uBlox CPU for $75.99.

I'd be a bit surprised if the power was much different considering how
much power the motors take.

Agreed.  Several projects have working (turn key afaict) autopilots for
the cortex m4f, but I guess the conservative thing to do is wait for the
ardupilot/arducopter port.

Sure, I suspect most folks just assemble it and either fly it live or
use qgroundcontrol or related app to set 3d way points.

Heh, cool.  Looks like the gopro is fairly common, as well.  I suspect
they just hit record before they launch.  I've been curious is gopro
supports some kind of API/SDK to allow similar.  They do offer a app
that can control the camera from a smartphone.

Sounds interesting to me.
