I just thought I'd share this board I've been sharing in other threads of the community:http://arduino.cc/forum/index.php/topic,71375.0.html
Given that this initial post was about "Very Small Arduino", I thought I would also share it with you here too.
The arduCHIP is a small compact board and breadboard-friendly based on the ATmega328. It has more or less the same functionality of the Arduino, but in a very small and compact package (20.6mm x 25.8mm).
It requires a 4.5-5.5V, or 1.8 to 4.2 if you run it at 8MHz, regulated power source making it the perfect companion for the arduSTAMP. The serial interface is fully compatible with the USB breakout board of the arduSTAMP or with sparkFun's FTDI basic. It also has a reset push button when prototyping and downloading.
The arduCHIP is meant for users that are familiar with the Arduino environment and are looking for a cost effective bare bones board to use on a space and budget constraint project (less than 7€ BOM including PCB). If you are not familiar with the Arduino environment it is recommend that you first go for the Arduino Duemilanove, the ONE (they are great boards and a very good starting point) or even the arduSTAMP. arduCHIP does not come with header connectors assembled (only the ISP and UART header) so that you can solder in any connector with the orientation you need for your application.
Here is an image of the IO mapping and PCB.
The entire project is opensouce, Eagle CAD files and an Eagle library file (to simplify using the board in any project) can be downloaded from:

I have currently run out of boards but there is a new batch coming.
If any one is interested in the PCBs, I've currently run out off but will be receiving an additional batch soon. I am sending them for:
- 2,2€ - bare board
- 13€ - fully assembled board
This includes shipping using regular snail mail.
Here are some images of an assembled unit.
