TDK 1204 piezo actuators.
2. Insert the terminal block plugs into the development kit’s terminal blocks.
3. Using a small slotted screwdriver, install TDK 1204 piezo electric actuator on terminals block
plugs. Pay attention to connect the red wire on the OUT+ terminal and the black wire on the
OUT- terminal. Refer to Figure 2 to identify location of OUT+ and OUT- on the terminal block.
4. Connect the development kit board to a USB port using the USB cable.
5. When the operation mode green LED is blinking and BOS1901 A/B status LED are solid green,
you are ready to go. Press on the piezo actuation to experience the piezo actuator button.

7Product Overview
The BOS1901-KIT has been designed to meet a multitude of needs. The main objective is to
demonstrate the capacity of the BOS1901 but also to help integrators in the development of haptic
effects and in its product prototyping.
The BOS1901-KIT is delivered with a graphical user interface (GUI) for ease of use but it is not required
to operate. It can save and restore its configuration at start-up. We will refer to operation without the
GUI by saying that the development board is used autonomously. It is configured in one of these
autonomous mode before shipping (see section 5). We will explain in more detail the so-called
autonomous modes in this document.
The BOS1901-KIT supports multiple operation modes:
Table 9: Operation mode list
Mode
Will help you to
Haptic
•Experience piezo haptic button emulation.
•Experiment with simple waveforms on various piezoelectric actuators.
•Experiment with piezoelectric device sensing.
•Evaluate any piezoelectric actuator for your application.
•Evaluate BOS1901 performance (waveform output, power consumption) in the
context of your application.
•Optimize BOS1901 operation using specific registers value.
•Command BOS1901-KIT waveform trigger from your system using an external
trigger signal.
Audio
•Easily experiment with various waveform shapes and amplitudes.
•Easily produce and compare various waveforms and identify the effects most
suited for your application.
•Play synchronous waveforms on both channels of BOS1901-KIT.
In Haptic mode, the GUI allows you to fire a given waveform from a variety of trigger mechanisms.
The BOS1901-KIT is used to test the capacity of the BOS1901 with various piezoelectric actuators. The
trigger events that can be used are: an action Play in the GUI, a falling edge on IO1, an action of pressing
and releasing the piezoelectric actuator. When the IO1 or the piezoelectric actuator are used as trigger,
the development kit can work without the GUI. The GUI also provides a section to read and write all
registers of the IC. For more details about this mode refer to section 8.5.1
In Audio mode, the development kit is detected as a standard stereo USB audio device by the PC.
We know that our customers require more flexibility and control over the waveform used for their
haptic effects. For these reasons, we put at your disposal the audio mode which allows you to have
complete control over the wave transmitted to the BOS1901 via the USB port. Your PC can select the
BOS1901-KIT as an audio card stereo output. You can configure audio mode settings using the graphical
user interface, but this mode is designed to work without the GUI. For more details about the audio
mode refers to section 8.5.2.
