3.5 Breakable units
Each channel is on a breakable PCB unit that can be used alone with a user-preferred development platform.
The available signals are:
‐
GND
0 V reference
‐
VDD
Main power supply for the BOS1901 (from 3 V to 5 V)
‐
VIO
Digital IO power supply (set to SPI signals voltage level, between 1.8 V and 5 V)
‐
MISO
SPI Master In/Slave Out signal
‐
MOSI
SPI Master Out/Slave In signal
‐
SCK
SPI Clock signal
‐
CS
SPI Chip Select signal (active low)
Refer to BOS1901 datasheet for a complete description on how to use and program the circuit.
The use of the breakable units with custom-made firmware is done at the user's own risk of causing
damage beyond repair to the BOS1901 circuit.

4.2 Software operation
The evaluation PCB appears as a speaker to the computer. The following operation example is made using
Audacity® software, but the use of any other software is also possible. Make sure the USB audio firmware is
installed on the evaluation PCB, refer to section for firmware installation/update procedure.
1. Connect the evaluation PCB with the USB cable, wait for green LED to light up and for red LED to turn
and stay off, after the firmware identification sequence
2. Start Audacity®, then select "File/Open…" to load "Audacity project - BOS1901-KIT.aup" file available
for download on
Boréas website
.
3. Select the appropriate Audio Host (see below):
