4.4.1 Connecting Xplained Extension Boards

It is also possible to interface legacy Xplained top-modules via the PROTO1 Xplained Pro board. The signal layout on the extension connector below the white line, i.e. pins 11 - 20 is identical to the J1 connector (communication connector) on the legacy Xplained series MCU boards.

So for legacy Xplained series top-modules that only uses this connector can be attached. Note that the extension connector on the Xplained Pro MCU board might not have all signals available due to lack of pin resources. This needs to be checked for each case. A mounting example is shown in the picture below with a sensor board.
