Dangerous Prototypes in the mail, but alas I had the wrong format chip on hand (I used the larger soic version on a project a month ago) so it had to wait a bit before I could populate it (Digikey didn't stock the ssop version, but Mouser did).
This board is a breakout for the MCP200 (described here). Overall it's relatively simple little board: the main chip from Microchip, four resistor/led pairs as indicators, a 12 MHz crystal with caps, a pullup for the reset line, some power filter and reserve caps and a ferrite (good for grabbing power off the usb line). The MCP220 is an odd little device though - it's happy on Windows, not so much on Linux or OSX (inherent in the way it interacts on the bus I think - I'm not all that familiar with the sub substructure and don't have enough free time right now to really dig into it).
If I had to change one thing about the board it would be to add labels for the output pins/holes... The one thing I really like about putting together other people's designs is that I always end up learning things - the differences in the way I would do it jump out - sometimes I end up liking my way better, sometimes I find a better way of doing something (and that's great).
