Chumby Hacker Board

Replacement: None. We are no longer carrying this product. This page is for reference only.

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.

Note: We are now shipping v1.0, which is the current version of the board.
