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 LVDS-pairs. The connectors provide also VCCIO voltages to operate the I/O's properly.

The maximum power consumption of the Carrier Board depends mainly on the mounted SoM's FPGA design running on the Zynq chip.
Xilinx provide a power estimator excel sheets to calculate power consumption. It's also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.

* TBD - To Be Determined soon with reference design setup.
Power supply with minimum current capability of 3A for system startup is recommended.
The Carrier Board needs one single power supply voltage with a nominal value of 5V. Following diagram shows the distribution of the input voltage '5VIN' to the on-board components on the mounted SoM:
