Our MP3 system was designed for a specific project. The development system is tested and available but the device package would need to be specified by the customer. The system can take streamed data from any valid source (CAN bus, ANT, BLE) and play an MP3 sample according to the value. The sound can be played direct to a small speaker or connected to an amplifier. The system has been successfully proven and is used to provide audio status updates to the user.
The yellowcog MP3 player can be attached to most of our hardware and here is the help on how to Audio MP3 Properties.
