CC3235MODSF LaunchPad™ Development Kit (LAUNCHCC3235MOD)
2.2.7.1 XDS110 USB Power
The most common power-supply scenario is from USB through the XDS110 debugger. This provides 5-V
power from the USB and also regulates this power rail to 3.3 V for XDS110 operation and 3.3-V to the
target side of the LaunchPad development kit. Power from the XDS110 is controlled by jumper J101.
When the board is powered from the USB connector, ensure that the jumpers are placed on the following
headers, shown in Figure 11.
