TUSS44x0 EVM for Ultrasonic Sensors User's Guide
To properly evaluate the TUSS44x0 EVM solution, connect and assemble the two boards as described in
these steps:
1. Stack the BOOSTXL-TUSS44x0 board on top of the MSP-EXP430F5529LP. Pin 1 of the MSP-
EXP430F5529LP must align with pin 1 of the BOOSTXL-TUSS44x0 LaunchPad-BoosterPack
connector (J1).
2. Position the power mode jumper for the intended use-case (see Figure 3 ).
3. Connect the transducer to the terminal block at J2.
4. Set the CFLT shunt(s) at J1 and CINN shunts(s) at J4 to most closely equal (or rounded up to) the
calculated capacitance values based on the transducer frequency.
5. Connect the micro-USB cable to a PC (see Section 2.1.2.2 ).
6. If using an external power supply, turn on the supply (see Section 2.1.2.2 ).
Figure 3 shows the assembled solution for the BOOSTXL-TUSS44x0 board configuration.

WARNING
This EVM contains components that are sensitive to electrostatic
discharge (ESD). Use proper laboratory techniques and equipment
to minimize the chance of an ESD or electrical overstress (EOS)
event.
2.1.2.2 Power Mode Jumper Settings
The BOOSTXL-TUSS44x0 EVM has an alternative power mode selector jumper block (J6). Depending on
the use-case, the assembled EVM can be powered from a variety of single or multiple power sources.
Table 1 lists each power mode with the jumper position of the power mode selector block.
