MSP430FR4133 LaunchPad™ Development Kit (MSP ‑ EXP430FR4133)
2.3 Power
The board was designed to accommodate various powering methods, including through the on-board eZ-
FET and from external or BoosterPack power (see Figure 9).
Figure 9. MSP-EXP430FR4133 Power Block Diagram
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. 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 and External Power Supply
Header J6 is present on the board to supply external power directly. It is important to comply with the
device voltage operation specifications when supplying external power. The MSP430FR4133 has an
operating range of 1.8 V to 3.6 V. More information can be found in the MSP430FR4133 data sheet
(SLAS865).
