chumby hacker boards (now available in beta)

chumby is now offering a “hacker” board, which is the guts of the chumby One, but modified to be more hacker-friendly: it comes with three high speed USB host ports, uses the power connector from the Sony PSP (instead of the weird, hard to find connector on the chumby One) and incorporates a variety of headers, such as Arduino-style shield headers and a 44-pin breakout header that gives you access to a lot of digital I/O and some analog inputs. There’s even a four-directional switch on board and some LEDs so you can do quick hacks that don’t require a video display for user feedback. Speaking of the display, while this board doesn’t come standard with an LCD, it does provide composite video output via a 4-wire 1/8″ jack so you can, by using an iPod video cable, plug the chumby hacker board into any TV that supports a composite video input.

The hacker board is currently being sold through Adafruit and also through Sparkfun as part of a limited-run beta program. The board is priced at around $89. The goal of the beta program is to collect feedback from users who purchase the board to fine-tune the design and to figure out what I/Os and accessories make sense to bundle with the board. Like the Arduino, we don’t integrate a lot of features onto the mainboard itself (keeps base cost low). Instead, we’d like to make sure that adequate I/O resources exist for developers to hack in the peripheral module they require to complete their project — or for more enterprising developers to build their own flavor of peripheral board and sell their own accessory.

There’s a few resources available to get people started on using the boards: a forum for general support and questions, and a wiki containing links to datasheets, schematics, and other more permanent documentation that people will find useful. Adafruit also has available a snazzy hackerboard page with tons of info, well-documented tutorials, and nice photos to boot.

One other point of note about the hacker board is that you can install a native gcc toolchain on it, so you don’t need to configure/install a cross-compiler on your host PC to develop for it. Heck, it’s got a 454 MHz CPU and plenty of disk space, so why not? Adafruit has a tutorial on how to install the compiler using a downloadable self-extracting script and a USB dongle. I’ve also heard rumors that an OpenEmbedded port is coming to the board soon, so stay tuned.

If you do end up purchasing a board and participating in the beta, please do contribute to the fora and wikis with your feedback. As always, happy hacking!

    Is there any relation between CHB’s Linux and what’s running on the Chumbys? Same distro base?

    • bunnie says:

      They are essentially identical distributions at this stage. The distro has some switches where it reads a hardware version number coded in an EEPROM and does the right thing based upon that hint (for example, activates the composite video instead of the LCD).

    Hello Bunnie,

    today I got my chumby guts kit and now I read, that there will be a developer version of the chumby one. Especially the breakout header I’d like to have on the guts kit. :o)

    I have one question. Two weeks ago I sent you an email – did you received it? I have some questions concerning hw manufactoring – it would be great, if you could help me a little bit. :o)

    not sure I understand what a hacker board is

    Does this board have the battery support circuit installed?
