Post from Bunnie (maker of the Chumby hacker board)…chumby hacker boards (now available in beta) « bunnie’s blog…
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 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!
