Power Control Input
The Zynq Ult MPSoC SOM works with 5V power input (VCC) from Board to Board Connector2 and generates
all other required powers internally On-SOM itself. SOM power can be enabled/disabled from the carrier board
through SOM Power enable pin in Board to Board Connector1. Also in Board to Board Connector1, Ground pins are
distributed throughout the connector for better performance.
For more details on Power control & Ground pins on Board to Board Connector1, refer the below table.
