453-00068-K2

The Aurawave AW100PA-A-INT (453-00068-K2) is a Bluetooth LE Audio Auracast™ transmitter platform designed to simplify broadcast audio development and reduce time to market. Built on the BL5340PA (nRF5340 + nRF21540 PA/LNA), it delivers strong RF performance and supports Bluetooth Core 6.0, Public Broadcast Profile (Auracast™), and LE Audio CAP/BAP roles for one-to-many audio streaming in venues, classrooms, and public systems. It supports both analog (line-in/out via onboard codec) and digital audio (I²S/USB) with configurable 16 kHz and 48 kHz broadcast modes for low latency or high quality. A 40-pin expansion header exposes GPIO, UART, SPI, I²C, and audio interfaces, while USB-C and AT-command control enable fast setup without deep BLE expertise. With prebuilt firmware, upgrade support, and flexible standalone or hosted operation, it provides a ready-to-integrate path from prototype to production Auracast™ audio systems.
