2.3 Quick start procedure
Refer to section for jumper options and for switch settings to ensure the evaluation PCB is in the
intended settings
Connect the selected actuator to the proper channel on P2A or P2B connector
Connect the evaluation PCB to a computer using the included USB cable, then wait for LED D1
(green) to light up and LED D2 (red) to turn off after the firmware identification sequence
Push the sensor with a finger to feel the feedback. Enhance the feedback experience by changing
DIP switch settings.
Using the Audacity® software, select a waveform to play on the actuator

3.1.1 Use BAT power (external power supply connection)
From default state:
Remove power to the evaluation PCB by unplugging the USB cable
Cut junction of SB3 jumper
Put a solder joint on SB2
Optional, solder a capacitor on C19 if additional decoupling is required on VBUS node
Plug the USB cable to the evaluation PCB for power and communication to the microcontroller
section
Apply an external DC source ranging from 3 V to 5 V on connector P5
Push and release "RST" button (S2), then wait for LED D1 (green) to light up and LED D2 (red) to
turn off
Note: the “USR” button (S1) has reserved usage on the current firmware.

Preliminary data
3.1.2 Use UPI feature
Warning - With UPI enabled, the energy recovery feature of the BOS1901 will accumulate energy in
C1A/C1B capacitor, causing COM voltage to increase. The user should make sure that VDD voltage
never exceeds the 5.5 V limit otherwise it may permanently damage the BOS1901. For instance, due to
its larger capacitance, it is not recommended to use the PowerHap™ actuators with 5 V supply and UPI
feature ON. Please refer to BOS1901 data sheet section 6.2.10 for more details.
From default state:
Remove power to the evaluation PCB by unplugging the USB cable
Remove solder joint on one or both SB1X, depending on the choice of UPI configuration
Plug the USB cable to the evaluation PCB, wait for LED D1 (green) to light up and LED De (red) to
turn off
3.2 Piezo actuators
TDK PowerHap™ piezo actuator specifications:
Type
Cymbal design
Polarity Red wire on "HV+" terminal
Black wire on "HV-" terminal
Range Unipolar -10 V to +60 V, use with switch SW1 at "OFF" position
(refer to section DIP Switch settings)
It is of utmost importance to not use the TDK PowerHap™ actuators in full-scale mode as it can get
damaged unless the waveform is properly designed to limit the output voltage between -10 V and +60 V.
Example waveforms are provided on Boréas website (www.boreas.ca/bos1901-kit).
Refer to section for a special output configuration, in which two TDK actuators can be connected on a single
BOS1901 circuit:
‐ "Load 1" with red wire connected to "HV+" and black wire on "VDD"
‐ "Load 2" with red wire connected to "HV-" and black wire on "VDD"
‐ Use of full-scale mode with output voltage limited to +60 V
‐ Toggle SW2 to single ended mode (ON)
