JP1 is provided to enable isolation between the device and the connected USB in higher-voltage applications. The area of isolation is defined by the white outline in the upper-left corner of the LaunchPad. JP1 has two removable shunts to separate the GND and 5V power of the USB region and the XDS110 and F28P55x MCU region of the LaunchPad. By default, both shunts are populated and the power is supplied by the connected USB, meaning that the USB is NOT isolated from the XDS110 and F28P55x MCU regions. If power isolation is desired, then remove the supplied shunts from JP1. In this configuration, one of the two external power options below are required.
Some applications do not require 5V to be supplied to the MCU region. In an isolated power application with JP1 shunts removed, supplying 5V to the XDS110 and F28P55x MCU regions is optional.
