Ezurio and Cloud2GND Launch Aurawave AW100 Series Modules to Simplify Auracast™ and Bluetooth® LE Audio Product Development

Aurawave combines Cloud2GND engineering, Ezurio module performance, and Nordic's nRF5340 technology to accelerate LE Audio innovation.

LOUISVILLE, Ky., Aug. 12, 2025 /PRNewswire/ -- Cloud2GND, a wireless engineering services firm, and Ezurio (formerly Laird Connectivity), a global leader in wireless module solutions, today announced the availability of the Aurawave AW100 series—a flexible, modular platform built to simplify and accelerate the development of Auracast^™ and Bluetooth^® LE Audio products.

Aurawave AW100PA modules are built on Ezurio's BL5340PA and BL5340 modules, powered by Nordic Semiconductor's nRF5340 SoC, with the BL5340PA variant adding the nRF21540 RF front-end module to extend range and improve connection robustness. The AW100PA board also integrates the high-performance AKM AK4558 audio codec chip achieving excellent signal-to-noise ratio and low total harmonic distortion (THD) for production-quality audio, outperforming typical development kit specifications.

Combined with Cloud2GND's Aurawave Audio Framework, the AW100 allows developers to quickly configure and deploy high-quality wireless audio broadcasting using a familiar AT command interface. Designed to support Auracast™ source functionality, LE Audio product development, and standalone or host-managed operation, the AW100 provides a complete hardware and firmware platform to serve both prototyping and production needs.

"Our goal with Aurawave was to make Auracast and LE Audio more accessible to developers and product teams," said Josh Toole, CEO of Cloud2GND. "By leveraging Nordic's dual-core architecture, Ezurio's high-performance modules, and our own embedded expertise, we've created a platform that works out of the box and scales to real-world applications."

The AW100 board includes onboard audio I/O (I2S, USB, and codec), a USB-C interface for power and data, and a 40-pin expansion header for GPIO and peripheral access. The included firmware enables device configuration via AT commands and supports key LE Audio roles without requiring custom development from scratch.

"The Aurawave AW100 makes it easier than ever to take advantage of the performance and range of the BL5340PA module," said Jonathan Kaye, VP of Product Management and Marketing at Ezurio. "Few solutions offer the combination of Nordic's nRF5340 with the nRF21540 RF FEM in a certified module, and Aurawave adds a high-quality audio conversion chip and the software layer needed to accelerate meaningful LE Audio deployments."

Key features of the Aurawave AW100 include:

• Auracast™ Source Support - Broadcast high-quality audio to multiple Bluetooth® receivers
• Long-Range Broadcast Audio - Free space range up to 250m
• AT Command Firmware - Easily configure and manage LE Audio behavior
• Bluetooth LE 6.0 - Compatible with third-party Bluetooth LE devices for a range of applications
• Audio Interfaces - USB for digital audio and AKM AK4558 for analog audio
• Standalone Mode - Operates independently when powered via USB-C or by the 40 pin header
• USB-C and 40-Pin Expansion - Simplified power, control, and peripheral integration
• Custom Firmware Support - Preloaded binaries with the option to flash custom builds via SWD

With Aurawave, Cloud2GND and Ezurio are delivering a ready-to-use platform that removes the complexity of LE Audio development. From early prototyping to real-world deployment, the AW100 gives engineers the tools they need to build the next generation of Bluetooth audio products.
