B. Schematic 

Below are two copies of the schematic for the TSWITX-G4-EVM. The first will be best when viewed on-
screen, as it is normally oriented and can be zoomed in on for readability. The second will allow better 
use in print-out form, as the landscape orientation allows a larger image to be provided. For each, 
annotation has been added to indicate which part of the block diagram each component is a member of.
