The StreamSDK is StreamUnlimited’s Linux-based full-featured modular audio streaming software platform, which offers a tremendous amount of customization options making it an all-purpose solution for almost every imaginable audio streaming device. Due to its integrated multi-room content distribution and full audio synchronization the StreamSDK is also a brilliant solution for multi-room audio streaming applications.

Besides conceptional consulting our task as design partner is to customize the StreamSDK to fit your project requirements. Customization includes the selection of supported streaming services, creation of suitable control interfaces to match your needs or even the development of custom drivers, in case you want the StreamSDK to become the central control unit of your audio streaming device. Furthermore, we support you with the integration of the user interfaces you want to provide.

Although the StreamSDK is platform independent, StreamUnlimited provides optimized and pre-certified processor modules ideally suited for StreamSDK applications.
The most popular module is the versatile Stream810, which relies on a powerful dual-core i.MX 7Dual audio CPU. It provides enough headroom for future applications while already being able to integrate all significant audio streaming services from Chromecast built-in, AirPlay, Bluetooth, Internet Music, USB to UPnP/DLNA. In a form factor of only 47 mm by 51 mm and powered from a single 5 V supply these modules deliver cutting edge streaming technology with the advantage of being easily integrated into almost every audio streaming device you can think of.

As design partner we deliver hardware integration consulting, customized reference base board designs, general design support depending on your special needs or even full hardware development.
