Xplained Pro
Xplained Pro is an evaluation platform which contains a series of microcontroller boards (evaluation kits)
and extension boards. Atmel Studio is used to program and debug the microcontrollers on these boards.
Atmel Studio includes ASF and Atmel START, which has drivers and demo code, and Data Visualizer,
which supports data streaming and advanced debugging. Xplained Pro evaluation kits can be connected
to a wide range of Xplained Pro extension boards through standardized headers and connectors.
Xplained Pro extension boards have identification (ID) chips to uniquely identify which boards are
connected to the Xplained Pro evaluation kits.

Xplained Pro Standard Extension Header
All Xplained Pro kits have one or more dual row, 20-pin, 100-mil extension header. The Xplained Pro
MCU boards have male headers, while the Xplained Pro extensions have their female counterparts. All
connected pins follow the defined pin description in the table.
Info:
All pins are not always connected on all extension headers.
The extension headers can be used to connect a variety of Xplained Pro extensions to Xplained Pro MCU
boards or to access the pins of the target microcontroller on Xplained Pro MCU boards directly.
