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.
