2.2 EVM Details
The following sections describe the various interfaces for measuring and controlling the configuration.
The configurations are in coordination with the settings of the PMIC. Understand that both the EVM
configuration and the settings of the PMIC must match is important. For example, if the GUI is used to
change the function of the EN/PB/VSENSE pin, then the jumper on J33 needs to be placed to connect
the push button to this pin.
2.2.1 Terminal Blocks
The terminal blocks are simple push and release terminals which can accommodate wire sizes up to 14 AWG.
Table 2-1
lists the terminal blocks found around the perimeter of the EVM. J9, VCCA, is the input voltage for the
regulators. The rest of the terminal blocks are for the BUCK and LDO outputs.

2.2.2 Test Point Descriptions
Numerous test points are provided to access voltages and signals. Test points marked with _S are designed for
sensing voltages only and are not designed to carry large DC currents.
