5Quick-Start
The BOS1921 and a piezoelectric actuator can be used together to implement the equivalent of a
button. Before being shipped, the BOS1921-KIT board is set up in this button mode, so that you can
experienceit without additional extensive configuration or software installation. If you have anactuator
such as TDK 1204, you can use it directly. Otherwise, the capacitors included in the kit can be used to
test the BOS1921-KIT.
1. Open the box, take the BOS1921-KIT board, the USB cable, the small driver boards, the
terminals block plugs, and either a piezo actuator or a capacitor.
2. Insert one or both the driver boards into the controller board.
3. Insert the terminal block plugs into the driver board(s) terminal block.
4. Using a small slotted screwdriver, install a piezoactuator on the terminal block plugs. Pay
attention to connect the positive wire on the OUT+ terminal and the negative wire on the
OUT- terminal. Refer to Figure 2 to identify location of OUT+ and OUT- on the terminal block.
5. Connect the development kit board to a USB port using the USB cable.
6. When the operation mode green LED is blinking and BOS1921 A/B status LED are solid green,
you are ready to go.
7. If using a piezo actuator : press on the piezo actuation to experience the piezo actuator
button.
a. If using a capacitor: either press the USER button on the board to set the board to
Audio mode and use an audio software to play waveforms (see section 8.5.2), or install
the GUI software to interact with the board (see section 8).
