Interface boards and MA2304xNS evaluation board
An MA2304xNS evaluation setup with an interface board can play audio without using software, as the interface
board's digital audio output format matches the MA2304xNS device default.
The MA2304xNS board's jumper and switch settings are preconfigured for basic BTL operation as default before
shipping.
Refer to the hardware user manual for interface board specifications.
