Table 2-1 describes the default jumper configuration for the EVM to power the device from a USB supply using an on-board LDO. Configure the EVM as specified in the table for initial bring up. The EVM can also be configured to use an external power supply by changing the configuration of jumper JP17 to connect Pin 2 to Pin 3.
