Linux Computer in USB Key Form-Factor 149

Posted by CmdrTaco from the put-that-in-yer-pipe-and-smoke-it dept.
PMBjornerud writes "A start-up located in the French Alps near Grenoble is readying a tiny ARM-based Linux single-board computer (SBC) in a USB key form-factor. Calao's USB-9260 USB key-sized SBC measures 3.3 x 1.4 inches (85 x 36 mm). It is based on an Atmel AT91SAM9260 processor, an SoC (system-on-chip) powered by an ARM926EJ-S core clocked at 190MHz. The SoC targets "advanced applications such as GPS application processors," according to Atmel. Here is a Spec sheet PDF. With a 10/100 Ethernet port, firewall usage springs to mind. Other interfaces are 2 USB host ports and room for an expansion card. Which should allow some creative uses. "

      I think the only advantage of this particular linux usb key is it's size. Otheriwse, the gumstix are a helluva lot more powerful and almost as small (think size of a gumstick).

        The Gumstix may have a higher clock, but they use the XScale microarchitectrue. The 926 is the same architecture, but the microarchitecture has superior performance, particularly with regard to memory access. I'd be interested to see real world benchmarks between the devices.

          It seems this one is quite a bit smaller as well. Furthermore, it has 256 MB flash instead of max 16 for the gumstix I saw. Then again, you can easily upgrade the memory of the gumstix using SD or compact flash. And the gumstix seem to have more options. Of course, it depends on the price as well. The gumstix seem to be pretty sweetly priced, we'll just have to wait for the prices of these.

        Yeah, except that all gumstix products put Ethernet on a daughterboard using a Hirose connector that's a complete non-starter in a severe high-vibration environment.

        This thing still uses an RJ45 connector which means it still can't be used in such a severe environment in its off-the-shelf form, but it's much easier to desolder a connector and solder a jumper cable to something like a MIL-C-38999 and pot the whole thing in epoxy than try to ruggedize those Hirose connectors (hopeless).

      • Gumstix now has a PXA270 based board that has USB host. As far as video, I think the best you could probably do is either a USB video device (assuming you can get a driver working) or the onboard LCD controller (which is picky to say the least because LCDs are evil).

      I disagree. I presume the device can run with only power (ie standalone). If so, and if it was cheap enough, stick one of these inside a Linksys WRT54GL case, attach it to an ethernet port, and you have a very nice parental filter dansguardian box. The Linksys itself isn't powerful enough to run dansguardian (not enough ram), but this device has sufficient ram. Or it could be used to augment the capabilities of linksys itself, like to do a PBX, or something.
