After a couple weeks of testing the production version I figured I would make my official announcement of my new board the the forums. The JKD Freeduino Hybrid.

The board is an Duemilanove/UNO compatible Arduino with both a 3.3V and 5.0V regulator.  It also has a level shifter for up to 8 I/O's so the board can run at 5.0V while interfacing and powering 3.3V devices.  The level shifter was designed to also allow you to connect your own reference voltage if you need to interface with a device that is neither 3.3V or 5.0V

One other unique thing about this board is that you can use both surface mount or through hole parts for most of the components.  This allows the same board to work as a kit with through hole parts.  There are a few options for connecting power, a jumper for disabling auto reset and you can use a crystal or a resonator.

The design is released under the CC SA 3.0 license.

Looks very nice. I sure would like to have a look at the schematic drawing, but the link doesn't work?

Sorry... try now.  I saw it error out on you so I just re-uploaded it.  BTW woopra is great for seeing what is happening live on your website.

Also I will have the Eagle files available soon.  I am still working on cleaning them up a bit.

Thanks, works now and the printer is spitting it out. I like arduino designs that go out of the box a little on features and options.
