Description

The TI WiLink™ 8 WL1837MOD ( https://www.ti.com/product/wl1837mod ) audio cape is wireless multi-room audio reference design used with BeagleBone Black (https://www.ti.com/tool/beaglebk featuring TI Sitara™ AM335x). The WiLink 8 device's WLAN capability to capture and register precise arrival time of the connected AP’s beacon is used to achieve ultra-precise synchronization between multiple connected audio devices. The WiLink 8 module (WL1837MOD) offers integrated Wi-Fi®/Bluetooth® /Bluetooth Low Energy solution featuring 2.4 GHz MIMO and antenna diversity on 5 GHz band.  It offers best in class audio solution featuring multi-room, Airplay® receiver, full audio stack streaming, support for online music services and much more. This TI Design will enable customers to design their own audio boards with  Wi-Fi/Bluetooth /Bluetooth Low Energy connectivity from our WiLink 8 module (WL1837MOD) and evaluate audio multi-room software on it.

The BeagleBone Wi-Fi Audio Cape extends a standard TI Sitara processor-based BeagleBone Black with WiLink 8 Wi-Fi /Bluetooth /Bluetooth Low Energy connectivity and an audio subsystem. The cape and relevant SDK are available at an additional cost from StreamUnlimited.

 

Features
  • Ultra-precise audio multi-room synchronization (< 20μsecs) between multiple speakers/capes
  • SDK supports rich set of online music services, UPnP, Airplay audio receiver, GStreamer, etc.
  • Wi-Fi dual band support on 2.4 GHz band (featuring 2x2 MIMO) and antenna diversity on 5 GHz band
  • Wi-Fi/Bluetooth (A2DP)/Bluethooth Low Energy co-ex and multi-role AP/station support
  • Stereo ADC/DAC support
