2.4.4

Primary and Secondary Side VIO

The bridge board can plug into a 3.3 V or 5 V system. The primary side input/output signalling uses the 
same voltage as the system. The secondary side voltage is independent of the primary side voltage. The 
secondary side signalling voltage is hard-wired to 3.3 V. If 5 V signalling is required on the secondary 
side, the PCB assembly must be modified in the following ways:

•

Remove the R1, R2, R3 resistors

•

Solder jumper wires (AWG22) between the 5V test pads and the SVIO test pads.
