This chapter describes the implementation of the relevant connectors and headers on SAM4S Xplained Pro

and their connection to the ATSAM4SD32C. The tables of connections in this chapter also describes which

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

The SAM4S Xplained Pro headers EXT1, EXT2 and EXT3 offers 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

. All headers have a pitch of

2.54 mm.
