2 Description
The BOS1211-KIT is a Development Kit to help
users get familiar with the BOS1211 Piezo Haptic
Driver IC.
Miniature PCBs are interchangeable allowing the
users to experiment with the actuator sizes
adapted to their platform.
This kit connects to associated PC software over
USB for easy programming of the BOS1211 and
manual generation of waveforms on the
connected actuator.
The piezoelectric actuator sensing capability is
used to emulate a button behavior. The sensing
and feedback parameters can be changed using
the software.
Many GPIOs and hardware features are accessible
to ease prototype building.

Page 5: Quick-Start Procedure
Important Note: this evaluation kit does not support hot swapping the driver boards in or out of the controller board. 1. When shipped the BOS1211-KIT-BRD-C is already loaded with the appropriate firmware. If the firmware needs updating, see section 5.4. - Page 6 The larger BOS1211-KIT-BRD-C is the main controller board. The smaller BOS1211-KIT-BRD-S, BOS1211-KIT-BRD-M and BOS1211-KIT-L driver boards must be inserted in one of the three card sockets. They may be inserted in any order. Not all sockets need to be populated.
- Page 7 User Guide – Preliminary 4.2 Changing the Miniature Driver Boards BOS1211 board components can be scaled depending on the piezoelectric actuator used. Each driver board (BOS1211-KIT-BRD-S, BOS1211-KIT-BRD-M and BOS1211-KIT-L) has been designed with components to support various actuator sizes. The table below indicates which driver board is best suited depending on the actuator capacitance.

Page 8: Compatible Firmware
BOS1211-KIT CONFIDENTIAL User Guide – Preliminary 4.3 Identifying the Boards Revision Number Each PCB board reference design and revision number (v#.#) are identified next to the “REF:” label. The following table indicates compatibility with the firmware and Devkit Controller software. - Page 9 SCK, MISO and MOSI connections are shared by all BOS1211 on the driver boards. Three chip selects (CSA, CSB and CSC) are required to access the chip select pin on each BOS1211 in the slots A, B and C. By default, a jumper on 5 V and VSPI forces the internal 5 V supply to be used. To use an external voltage domain, remove this jumper and connect VSPI to the external supply.
- Page 10 USER is not used by the current firmware. 4.4.8 LED A total of 5 LEDs are present on the development kit BOS1211-KIT-BRD-C board. D1 (green LED) and D2 (red LED) are located near the USB connector. They indicate firmware revision during boot up and provide information on development kit operation.

Page 17: Basic Tab
For the selected mini-board tab, the Basic tab is used to send waveforms to the evaluation board. This section describes each parameter and control. Sync/Desync All Button When pressed, all connected boards will play the same waveform using BOS1211 SYNC feature. Depress the button to play waveforms on individual boards. Save in Memory This button will save the current configuration to the MCU internal memory. - Page 18 BOS1211-KIT CONFIDENTIAL User Guide – Preliminary Figure 8 Main application window when connected - Basic tab Sensing When checked, the actuator will behave like a button, playing the waveform when pressed and released. The release waveform amplitude is set to 75% of the press waveform amplitude. This box must first be checked to adjust the sensing parameters.

0x32 value instead of the expected 0x30 value. If this is the case, then 0xE400 need to be sent on the SPI interface to the BOS1211. Then the CHIP needs to be checked again for verification. Once it outputs 0x30, normal execution may continue. -
Page 35: Notice And Warning
The piezoelectric actuator is connected between OUT and VIN. When measuring these signals using an oscilloscope, use a separate probe on each terminal of the actuator. Never connect the ground of a probe to one of these terminals. Doing so might damage the BOS1211-KIT and/or your oscilloscope. BT002BDK01.05 – Issue 5... -
