3.9 XPRO Header (J900)
The PIC32-BZ6 Curiosity Board includes one XPRO standard extension male header (XPRO header) (J900) to connect to the Microchip QT7/T9 Xplained Pro kit. The Microchip QT7 Xplained Pro kit is an extension board that enables the evaluation of self-capacitance touch using the Peripheral Touch Controller (PTC) module. For more details, refer to the QT7 Xplained Pro Extension Kit (ATQT7-XPRO).
The following table provides details about the pinout definition.
