The BeagleBone Black, shown below, is the latest offering from BeagleBoard and seems to be aimed straight at the Raspberry Pi price point. Since I am interested in the physical interface side of computing I was very interested to see this computer seeming to merge an Arduino with an ARM processor based computer.
I have only started to work with this device but on first blush I would say that it looks and feels like a more professional device than the Raspberry Pi. It has a faster processor, though less capable graphics, and as I said, a full range of physical interface capabilities including on board, 12bit, Analog to Digital Conversion.
More to come later including a comparison of the environments that I have been testing.
