The Atmel® STK®600-RC064SAM-72 (STK600) is a routing card to support the 64-pin version of the Atmel SAM D20 ARM® Cortex-M0+ based microcontroller on STK600. The STK600 does not support programming of the SAM D20. However, it does work as a breakout board for IO-pins and programming interface, as well as being able to power the device and provide clock signals.
