Connectors
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.
I/O extension headers
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
standard extension header specified in
2.54 mm.
