2.3.1
eZ-FET USB Power
The most common power-supply scenario is from USB through the eZ-FET debugger. This provides 5-V
power from the USB and also regulates this power rail to 3.3 V for eZ-FET operation and 3.3 V to the
target side of the LaunchPad development kit. Power from the eZ-FET is controlled by jumper J101. For
3.3 V, make sure that a jumper is connected across the J101 3V3 terminal.
2.3.2
BoosterPack Plug-in Module and External Power Supply
Header J6 on the board supplies external power directly. Comply with the device voltage operation
specifications when supplying external power. The MSP430FR5994 has an operating range of 1.8 V to 3.6
V. More information can be found in the
