I see you followed the official arduino mega design in that you don't breakout 16 of the I/O pins, is there a reason you did that?

Hi Lefty
The main reason is to follow the Arduino standard but it is also a design issue. I can't see any reson to have more than 64 i/o on this small breadboard.

I understand that, but I'm always somewhat disappointed when a module/board supplier doesn't allow the user access to a chips full complement of features. I understand that design decisions almost always have to make trade-off decisions at times, however I will usually pick the design that allow full access, as when I selected the Seeeduino mega1280 board over the original arduino mega1280 board for just that reason.

I see an amount in €'s
Which Country?

We are actually from Sweden but we give prices in Euro so it's easier for everyone to calculate 
I have made a website for our two pcb's on http://www.expansionboard.org. I will post updates and some info about us later on.
This looks very interesting. How many serial ports does it have?

Hello Rudi.
This board has all of the 4 UART from the AtMega2560. So basically you have 5 UART including SoftwareSerial.

Where can I get a board like this?
