I/O Connector Description

Three connectors are placed to supply the device under test (DUT) to get access to different signals for
programming or to measure.
CON1 is the supply connector to provide the battery voltage and offer a connection to SPI.
CON2 is the output connector to deliver the output voltage of the different regulators.
CON3 is a connector to either the SPI of an application circuit, or the optional TIGER board which
provides a universal serial bus (USB) to SPI connection.
