  • This is a "dumb" display; it does not have the onboard GOLDELOX graphics controller that the more expensive displays contain. The BB has plenty of horsepower to drive it directly.

  • Short answer: yes. I have both S2 and S2/Pro devices feeding data to pachube via ConnectPort X2 running XIG.

  • FWIW, the latest version of XIG (1.4) makes these a lot easier to work with. Automatically feeding sensor data from a network of XBees to cloud services (iDigi, pachube, thingspeak, etc) is easily accomplished.

    Custom application development with Python and Dia is fairly straightforward, but the tiny amount of memory in the X2 is a maddening constraint. The XIG team has done an excellent job shoehorning functionality into the device.

    BTW, I'm not associated with any of these projects directly, am just a home automation / IoT geek.

  • To clarify, the gateway contains an XBee Pro S2. It does not come with an extra XBee.

  • Interesting - though I'm curious how this compares with Atmel's own ATAVRSBIN1 board at 60% of the price: http://www.atmel.com/dyn/resources/prod_documents/doc8354.pdf
    Worth a look...

  • Take a look at the CymbNet EnerChip CBC5300 as well, have used them in a couple of solar designs: http://goo.gl/PChfC
    Nice discrete solution, includes caps and 100uAH thin-film batteries on board a DIP24 package. Package supports piezo, solar, thermo, AND RF in single package.
    This breakout is a toy in comparison, and is only a single part of a complete energy harvesting solution.

  • This is the first product I've purchased from SFE that left me really disappointed (and I've bought a good chunk of their catalog). Terrible contrast, no backlight when connected via USB, etc. I think it's just a lousy display, not any fault of Sparkfun.
    If you want a bright little display, look at the 4D Systems serial OLED displays instead. Bright, crisp color with a simple serial interface.
    And SparkFun - take a look at the 4DisplayShield 160 or similar to replace the color LCD shield, this one's a turkey.

  • I use these for quick Arduino proto shields. A couple of rows wider and they would be a perfect fit - as it is I prefer them to the other proto shields available because of the amount of real estate they provide.
    Note that bridging adjacent cells is not a simple task without a bit of wire - the cells REALLY like to stay isolated. This is extremely nice for prototyping as it helps to eliminate inadvertent shorts, but can be frustrating when you actually WANT to short adjacent cells .

  • I've got one of these and it's very, very handy. To answer the questions:
    1) It supports the series 2 XBees. It is NOT compatible with the series 1 devices.
    2) It contains an XBee Pro S2 with chip antenna.
    3) It allows you to WIRELESSLY update firmware on remote XBees. This is a HUGE advantage if you have a lot of XBees.
    As others have mentioned, this can't be directly compared to an Arduino + XBee solution; it provides an internet/ethernet gateway, embedded web server, XBee management, and an integrated Python environment for running custom applications. You get a lot of functionality at this price point.
    It also gives you access to the iDigi.com cloud-based service which allows you to remotely administer these devices from the internet. Cool possibilities there as well.
    I was extremely happy to see Sparkfun beginning to carry this, as the digi store is absolutely terrible; just finding the device on their site is a nightmare.
    Found out about this via Robert Faludi's "Building wireless sensor networks" book, which I also highly recommend. I'm not associated with any of these items/books, have been impressed with them.

No public wish lists :(
