1.10 Xplained Pro Extension Standard Header
The Curiosity PIC32MZ EF 2.0 Development Board has an Xplained Pro extension compatible interface that enables
using the existing extension boards. This interface consists of a dual row, 20-pin, 100 mil, 90 degree extension male
header. Xplained Pro extensions have their female counterparts. The extension headers can be used to connect a
variety of Xplained Pro extension boards or to access the pins of the target MCU directly. All connected pins follow
the defined pinout description as shown in the following table.
Note: All pins are not always connected.
