The TI WiLink™ 8 WL1837MOD audio cape is a wireless multi-room audio reference design used with BeagleBone Black (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 reference 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 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.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
