4.2.1 Extension Headers
The T10 Xplained Pro implements three Xplained Pro Standard Extension headers (see Xplained Pro Standard Extension Headers) marked with EXT1 in silkscreen. These headers make it possible to connect the board to an Xplained Pro MCU board with a capacitive touch-enabled microcontroller. The pinout definition for each extension header can be seen in the tables below.
