After too much overthinking about choosing a controller, I have chosen a Pandaboard ES
It's working very well with Ubuntu, specially with the Sandisk ultra class 6 card which performance is pretty good even with GUI; far better than the Kingston HC class 10. By the way, the Ubuntu installation is very easy.
I have tested it controlling the AX-12 with C++ and C# (with Mono) code. With C# I have found a very strange problem when working with USB2Dynamixel at 1M, it doesn't work.
I have tried a very simple battery solution, four 1.2V AA GP ReCycko rechargeable batteries and a battery holder and it last around 30 minutes, with no USB device connected (except the USB2Dynamixel, of course)
And, finally, my question is about the best approach to interface to +3.3V or +5V sensors. A level shifter like this one?

Hi
thanks for posting.
Yes, this level shifter should work fine
there are so many new ARM boards thanks to the Chinese A5 and Rasberry-Pi that it is difficult to know what to get.
The panda has been around for a while and had good price/performance a couple of years ago. You still get the best support for this board and beagle thanks to the big US online hobby community that uses these boards and solves kernel issues.

Thanks Limor
Yes, there is a very good community and Ubuntu support, I really need it
, but IMHO it's a little pricey.
In a few days I should receive a Raspberry too, I think that this cheap and so popular board as Bioloid brain could be very interesting.
By the way, this one of the first prototypes of a new Bioloid based "creature" with Pandaboard

Hahaha, thanks Limor.
My friend Pepe, and also Bioloid player, has created the wood base with a milling machine and I am trying to get an easy system to attach different boards to it using Lego Technics for prototyping.
