Other Headers

In addition to the Xplained Pro standard extension headers, SAM4N Xplained Pro has three additional
headers with spare signals that offers access to the I/O of the microcontroller that are otherwise not easily
available elsewhere or might be favorable to have collected together. All headers have a pitch of 2.54mm.
