This chapter describes the implementation of the relevant connectors and headers on SAM D20 Xplained Pro

and their connection to the ATSAMD20J18A. The tables of connections in this chapter also describes which

signals are shared between the headers and on-board functionality.

The SAM D20 Xplained Pro headers EXT1, EXT2 and EXT3 offer access to the I/O of the microcontroller

in order to expand the board e.g. by connecting extensions to the board. These headers all comply with the

pitch of 2.54 mm.
