The TEB0729 Carrier Board's Board-to-Board Connectors (B2B) have the same pin-assignment as the mounted Zynq SoM due to its hermaphroditic structure. By this connectors, the MIO- and PL-IO-bank's pins and further interfaces of the Zynq SoM can be accessed. A large quantity of these I/O's are also usable as  as LVDS-pairs. The connectors provide also VCCIO voltages to operate the I/O's properly.
