X-NUCLEO-CCA01M1
Sound terminal expansion board based on STA350BW for
STM32 Nucleo
Data brief
Description
The X-NUCLEO-CCA01M1 is an expansion
board based on the STA350BW Sound
Terminal® 2.1-channel high-efficiency digital
audio output system.
It can be plugged on top of an STM32 Nucleo
board and is compatible with the ST morpho
connector layout. It enables the output of digital
audio streams to a speakers pairs connected
directly to the board and allows the evaluation of
the STMicroelectronics STA350BW digital audio
output component. Up to two X-NUCLEO-
CCA01M1 expansion boards can be plugged on
top of the same STM32 Nucleo host in order to
build a four-channel digital audio output system.
The communication between the STM32 MCU
and the STA350BW device is performed through
the I²C bus interface for setup and control
purposes and the I²S bus for digital audio
transmission. A dedicated connector is available
on the board in order to supply the power source
for the output stage.
