A Basic board to test the Atmel SAMD09. On board there is also a CH340 uart to usb bridge
Build this board to getting started with the SAMD microcontroller family after I made the mistake to try the much bigger SAMD21 first. The SAMD09 used here is he smallest from this family and therefore has the shortest (still 709 p.) datasheet. I think this board will be, as my other microcontroller breakout boards, very useful for an early prototyping phase on breadboard. So far I quite like the SAMD09. If you compare it to the the ATmegas there are a lot more possibilities. Maybe this is the Arduino Nano killer for me.
