BeagleBone Wi-Fi Audio Cape

The Wi-Fi Audio Cape extends a standard TI Sitara based BeagleBone Black with WiLink™8 Wi-Fi/BT/BLE connectivity and an audio subsystem.                                                                

Analog audio in- and outputs are provided which support sound reproduction at up to 384 kHz sampling frequency. Audio clocks can be synchronized at sub microsecond’s precision between multiple devices for stereo and multichannel audio. The mainline Linux based StreamSDK of StreamUnlimited combines this highly accurate synchronization with a rich set of online music services, a customizable user interface offering both local control and display and control via iOS and Android devices.Order button
