Modular 

Gateway implements a variety of peripheral interfaces through the SODIMM-200 connector to 

connect with i.MX6UL based SOM. 

This section provides detailed information about electrical design & 

practical consideration of different peripherals of Modular Gateway. 

The architecture block diagram of Modular Gateway board is shown as below:
