The Atmel ICE Breakout is designed to make connecting to the Atmel ICE programmer and debugger easier.  It includes SAM20, SAM10, AVR10 and AVR6 0.1" headers.  As well as breaking out the 100mil ICE headers it provides several power inputs for powering the target device.  These inputs include USB, 0.1" headers and 4mm banana sockets.  A 3.3V regulator is included for regulating the 5V USB input.
