AudioBL Combo Bluetooth/Toslink/SPDIF Coaxial 3 in 1 Audio Interface Board

AudioBL Combo is a 3-in-1 audio interface board that supports Bluetooth, Toslink/SPDIF, and coaxial inputs. It can convert Bluetooth/Toslink/SPDIF signal to I2S output. You can use it to work with our DSP amplifier board and build a multi-audio interface amplifier board. No external power supply is required; simply plug it into the AudioB interface socket for immediate operation.

A short press of the onboard button enables cyclic switching of audio sources. The board also supports the connection of external RGB LEDs and buttons for extended use. Equipped with a QCC3031 Bluetooth chip, the AudioBL Combo can be preloaded with TWS (2 boards can be linked together) or Party mode (multiple boards can be linked together) firmware on the Bluetooth module. The USB-C port on the board is dedicated to Bluetooth programming, allowing you to independently modify Bluetooth settings or update the Bluetooth firmware as needed.
