4.1 Kit Assembly Overview
The kit is an assembly of many boards as shown in the figure below.
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.
Use a terminal block to connect the actuator. Red wire must be connected at OUT pin, and black wire
must be connected at VIN pin. The provided terminal blocks are insertable in terminal block socket for
easy assembly and interchanging.
Connect the 12 V power supply to the controller board and connect the USB connector to a PC USB data
port to interface with the GUI software. It is possible to connect the USB cable to a USB charger port,
this limits the board behavior (see section 5.3.2).

Important Note: this evaluation kit does not support hot swapping the driver boards in or out of the
controller board.
Before changing driver boards, first disconnect both the USB cable and the 12 V supply. Then disconnect
the insertable terminal block joining the actuator. Change the driver boards for the desired
configuration, then successively reconnect the terminal blocks, the 12 V supply and the USB cable.
Although one of each driver board is included in the development kit, it is possible to get additional
driver boards as needed. Therefore, it is possible to connect many identical boards on the same
controller board.

4.4 BOS1211-KIT-BRD-C Other Hardware
The controller board has additional hardware features to expand the board functionally when testing
actuators and building prototypes. These features are described in this section.
4.4.1 Probe Hooks
Probe hooks have been inserted around the board to ease connection of instruments for measurement
of supplies when debugging.
4.4.2 Expansion Port
An expansion port is available to provide test point access to the SPI I/Os. This port is labeled TPSPI in
the BOS1211-KIT-BRD-C schematics. It is initially unpopulated but can be using a Sullins Connector
Solutions model number SBH11-NBPC-D12-SM-BK or equivalent.
4.4.3 GPIO
General-purpose inputs and outputs are provided to easier integration of the development kit in a
prototype. For example, digital inputs may be used as trigger inputs to fire the waveforms or to send
information from the system to the development kit.
Using these GPIOs implies to modify the firmware to support them. However, they are already physically
implemented and routed to the MCU. They only need to be activated in the firmware software code
project.
There are 8 inputs and 8 outputs available on header connectors at the bottom of the board. A jumper
is initially shorting VIO-IN and VIO-OUT with the board 3.3 V pin so they are referenced to the board
main 3.3 V supply. To use an external supply, remove the jumpers and connect the external voltage
supply to the VIO-IN and VIO-OUT pins. The external supply must be in the 1.65 to 5.5 V range. VIO-IN
and VIO-OUT may have different supply levels.
Refer to the board schematics in section 7.1 for MCU pins numbers corresponding to the inputs and
outputs used.
4.4.4 ADC and DAC Connections
One DAC and four ADC pins are made available to the user. These connections are buffered to protect
the controller board. These signals cannot exceed the board 3.3 V supply level.
Using these implies to modify the firmware to support them. However, they are already physically
implemented and routed to the MCU. They need to be activated in the firmware software code project.
4.4.5 External SPI Master
All BOS1211 actuator driver chips are controlled via the SPI interface using the PSoC6 MCU as master. It
is, however, possible to bypass the MCU and use an external SPI master. This can be useful when trying
to connect the BOS1211 ICs directly to an external system.
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.

BOS1211-KIT CONFIDENTIAL
User Guide –Preliminary
BT002BDK01.05 –Issue 5 © All rights reserved 2020 Boréas Technologies Inc 10
Finally, set the SPI Select switch to the EXT position to select the external SPI master, or leave it at the
INT position to use the MCU as the SPI master.
4.4.6 External I2C Master
Connections are provided to allow for an External I2C Master to be used. This is useful to connect the
controller board to a system that requires I2C connectivity.
Initially, this function is not implemented in the firmware. The firmware source code must be modified
for the MCU to act as an I2C slave. However, the board makes it possible if needed and allows for an
external voltage domain to be used as well.
By default, a jumper on 3.3 V and VI2C forces the internal 3.3 V supply to be used. To use an external
voltage domain, remove this jumper and connect VI2C to the external supply. Note only a 3.3 V or 5 V
supply may be used.
4.4.7 RST and USER Push Buttons
RST push button forces a reset of the MCU and the firmware.
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. See sections 5.1 and 5.2 for
details.
D3A, D3B and D3C (orange LED) are located next to their associated channel slot card and are used to
indicate that channel current status (see section 5.2).

5Firmware
5.1 Identifying the Firmware Revision Number
When powering up the development kit, LEDs will show the firmware revision number and then the IC
revision.
After the 10-second bootload window while both LEDs are on (for firmware revisions below 1.5.0), the
green and red LEDs flash to indicate the firmware revision number. For a firmware revision X.Y.Z with
major revision X, minor revision Y and patch revision Z, the green LED will flash X times, then the red LED
will flash Y times and then both LEDs will flash Z times. The routine will execute twice. If no problem
were detected, the green LED will stay lit otherwise only the red LED will light up.
5.2 LED Indicators
The MCU continuously monitors the status of each channel. The status is then shown by the associated
LED (D3A, D3B, D3C). If an error occurs for a channel, the red LED (D2) will light up and the corresponding
channel orange LED will flash a number of times to indicate the error (see Table 5). The error will be
indicated in cycles until the issue is resolved. When no error is detected and a slot card is inserted, the
corresponding LED will stay lit.
Table 5: Channel LED flashing routine when in error

5.3 Modes of Operation
5.3.1 PC Connected
When the board is connected to a PC running the Boréas DevKit Controller software, it will communicate
with it and the user can control the board using the software interface.

BOS1211-KIT CONFIDENTIAL
User Guide –Preliminary
BT002BDK01.05 –Issue 5 © All rights reserved 2020 Boréas Technologies Inc 12
5.3.2 Persistence Mode
When booting the BOS1211-BRD-C evaluation board, the firmware will enter the Persistence mode. In
this mode, the board will behave as programmed by its internal memory. The memory can be set from
the PC software to a specific feedback waveform and trigger mechanism. When using the external
trigger, a rising edge on the GPIO input pin 0 will trigger the waveform stored in memory. If sensing was
activated when programming the memory, sensing will be activated in the Persistence mode.
When the Boréas DevKit Controller software is connected, any configuration push to the board will
override this Persistence mode. The Persistence mode can be restored by rebooting the board, either by
pressing the RST button or by unplugging the USB cable.
This mode will operate whether the board is connected to a PC USB port or a charger port.
5.4 Firmware Installation/Update Procedure
5.4.1 Kits Shipped with Firmware Revision Prior to 1.5.0
The BOS1211-KIT is provided out of the box with a firmware for use as USB Serial Device.
