Dan Watson has designed a development board for the Atmel SAM D09 microcontroller:
The Atmel SAM D series of 32-bit microcontrollers includes several devices, each with a long list of features at great prices. Perhaps the best known of the series in the maker community is the SAM D21 due to its use on the Arduino Zero. However, there are several other devices in the product line that are worth taking a look at. The smallest of the bunch is the SAM D09 that comes in a 14-pin SOIC package. The 14SOIC package is one of my favorites. It is easy to solder, easy to break out on a PCB, and takes up little board space. I decided to order some SAM D09C chips and design a small development board in order to learn more about the capabilities of the device.
