Aurawave AW100 Series
Cloud2GND has partnered with Ezurio to release a new application module that combines Nordic Semiconductor’s class-leading LE audio chipset with a high-quality audio interface and a high-level API for easy module integration.



Broadcast Better with Aurawave
The Aurawave AW100PA module, paired with the Aurawave Audio Framework, lets product manufacturers rapidly add Auracast™ and LE Audio functionality to existing and new product designs.
Auracast™ allows companies to deliver high-quality audio to multiple Bluetooth® receivers at once. Perfect for public spaces, venues, and personal audio systems.
The Aurawave AW100PA is built around the Ezurio BL5340PA Series Module and the AKM AK4558. The Ezurio module combines the Nordic nRF5340 chipset with the Nordic nRF21540 Front-end Module to achieve long-range low-power Bluetooth performance, perfect for broadcast applications.
Beyond Auracast™, the AW100 series will provide flexible Bluetooth LE Audio product solutions, helping you bring next-gen audio features to your products faster, without the usual development overhead.
The AW100 Series modules feature the Cloud2GND Aurawave Audio Framework. A complete LE audio software subsystem that implements key LE audio features in a simple-to-integrate package with a flexible AT command interface.
The first release of the framework focuses on Auracast broadcast capability. A simple AT interface combined with analog and digital inputs makes adding an LE Audio broadcast possible with just a few lines of code or a stand-alone configuration.
