DRV2625 Haptics BoosterPack™ Plug-In Module

Figure 8. Assembling Boards

The LRA load to be tested can be glued to the LRA space section. Then, the PCB will work as the LRA
mass. Once the LRA is fixed in the LRA space section, it must be connected to the actuator terminal. The
BoosterPack is now ready to be powered on.

Capacitive Touch Buttons

Once the boards are aligned and plugged, and the LRA load is connected, the MSP-EXP430FR6989
LaunchPad can be connected to the PC through a micro-USB cable. The LaunchPad will be powered on
and enabled immediately. Consequently, the BoosterPack will be energized and initialized with the default
configuration.

The MSP430FR2512 microcontroller on the BoosterPack can be used now to interpret the touch buttons
being pressed.
