3.4.1 Xplained PRO Extension Header

All Xplained PRO kits have one or more dual row, 20-pin, 100 mil extension header. Xplained PRO extensions have their female counterparts. Note that all pins are not always connected. All connected pins follow the defined pin-out description in the Table 3-2.

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 MCU on Xplained PRO MCU boards directly.

The PL460-EK is a Client companion board for the PIC32CXMT family of EK/DBs, SAM4CMx-DB family, SAME70-Xplained and SAMG55-Xplained boards. All these boards include an Xplained PRO (Host) connector, and PL460 includes a Xplained PRO connector accordingly (Client). See Table 3-10 with the analysis of system interfacing with the required Xplained PRO host platforms.
