One of the things I have been meaning to write about for some time is how we provided flexible interfacing when we developed the Tile Carrier Card. Of course, we wanted the Embedded System Tile to be able to communicate with both the Raspberry Pi Compute Module and the Pmod interfaces available on the board.
