The Aurawave AW100 module simplifies Bluetooth LE Audio and Auracast product development by combining proven hardware with ready-to-use firmware. Cloud2GND and Ezurio (formerly Laird Connectivity) developed the module around Nordic Semiconductor’s nRF5340 dual-core SoC, while select models include the nRF21540 RF front-end to extend range and strengthen connections. The module integrates an AKM AK4558 audio codec that delivers high signal-to-noise ratio (SNR) and low total harmonic distortion (THD) for reliable, high-quality audio. This design shortens development time, streamlines certification, and speeds product integration.
The Aurawave AW100PA variant is based on Ezurio’s BL5340PA and BL5340 modules, leveraging the nRF5340 SoC and the RF FEM for enhanced performance in demanding use cases. Capable of operating as a standalone unit or integrated into a larger system, the module comes with Auracast source support and LE Audio features built in. From lab prototyping to mass production, the AW100 provides a flexible platform that accelerates development while maintaining robust audio and connectivity performance.
Aurawave AW100 module specifications:
The Aurawave AW100 module uses Ezurio’s BL5340 and BL5340PA modules powered by Nordic’s nRF5340 dual-core SoC, which integrates Arm Cortex-M33 application (128 MHz) and network (64 MHz) cores. The AW100PA variant includes the nRF21540 RF front-end module to extend range and improve connection robustness. An AKM AK4558 sigma-delta codec manages audio processing, delivering excellent signal-to-noise ratio (SNR) and low total harmonic distortion (THD). For input and output, the module offers a 3.5 mm analog line In/Out jack along with I²S digital audio through a 40-pin expansion header.
Connectivity and control options include a USB-C port for power, digital audio streaming, and AT command access, along with a flexible AT-command interface supported by the Aurawave Audio Framework. The module supports Auracast source broadcasting, enabling multicast wireless audio to multiple Bluetooth receivers, with long-range BLE audio transmission up to around 250 m in free space. Developers can operate the AW100 as a standalone device powered over USB-C or integrate it into a larger system via its 40-pin header exposing GPIO, I²C, SPI, UART, and I²S. For customization, an SWD header allows firmware flashing through Nordic development tools, making the module adaptable for both prototyping and production environments.
The Aurawave AW100 module comes with the Aurawave Audio Framework, a firmware layer that enables Auracast broadcasting and LE Audio through a simple AT-command interface. Developers can configure audio inputs, set broadcast parameters, manage sources, perform firmware updates, and reset settings with ease. The module operates in standalone mode via USB-C, broadcasting analog or digital audio without a host system, or it can be integrated into larger designs through its 40-pin header, supporting I²S, USB, and line-level interfaces with control over UART or USB. This flexibility allows rapid prototyping and scalable deployment of LE Audio solutions across consumer, commercial, and industrial applications.
