World's Smallest Linux Box Fits in RJ-45 Jack

Posted by timothy on from the nearly-swallowable dept.

An anonymous reader writes "German electronics company Kleinhenz is shipping a network-enabled Linux system built into an RJ-45 Ethernet jack. "Picotux" has a 55MHz ARM processor, 2MB of Flash, 8MB of RAM, a serial port, and five lines of GPIO. It measures 0.75 x 0.75 x 1.4 inches (19 x 19 x 36mm), and weighs 0.64 ounces (18 grams), packaged in a metal housing. A wireless 802.11 version appears to be on the horizon, too. So, if you've ever wanted to network-enable, say, a robot, boombox, or model airplane, this could be the system for you." Is this really the world's smallest? It looks a bit chunkier than a tiny gumstix machine.

    ...more like a Needle.


    For only Eur 99, though, a fair deal if you need a whole lot of tiny servers for something. Who needs virtual servers, when you can stick real ones at the end of each ethernet cable?

  2. Power by BrookHarty · · Score: 5, Interesting

    First thing I thought, if you could power it with ethernet, you could put this in remote locations for sensors. But 250mA is pretty efficient.

    I could see a use for the wifi+serial setup, you could put this on older serial based nodes and remotely access them. Big market for HVAC when everyone wants them to replace hardware. Our schools here in the Washington state is saving millions by using linux and other technology than going with Honeywell or some other company to rip out the entire system and replace with modern (aka expensive) controls.

    A wifi serial setup would be cool, to pop in a router, and then access via my laptop, so I dont have to run a wire when I'm testing or racking it up.

    Lots of uses. Very cool idea.

    No, what's needed is an advancement in the chip at the center of this device. Currently it only has one MAC and PHY for ethernet. The next evolution of this chip should have 2 MAC/PHY. Package it in a metal case with RJ-45 at *both* ends and flash a minimal Linux+FW into it.


    Then it truly will be a "bump in the cable" as one person said.

  4. Dual-End it by chill · · Score: 5, Interesting

    I mean 2 ethernet ports, making it look like a cross-over connector, and you've have a great firewall gizmo.
