I'm a newbie of the SONSIVRI. I is not familiar with English. So, I ask for your understanding.
Several years ago, I have designed a development board using ATMega128. This development board give me a lot of help to learning the concept of the AVR. Although Mega128 is not the latest chip, if you are planning the design of the test board using XMega series,this board's concept will be little help.
Depending on your firmware design, you can use it for a variety of purposes, I think. Actually, I've try to use it to replace the Lego RCX's controller. I was able to use most of the Lego RCX sensor.
