As smart audio devices evolve rapidly, the commercialization of the Bluetooth LE Audio standard has become a key driver for product innovation. New features like the LC3 codec, low-power connectivity, and broadcast audio are redefining the user experience and design possibilities for wireless audio products.

The Qualcomm QCC5181 audio SoC serves as the core of this Bluetooth (BT) ses modülü. It integrates dual Kalimba DSP cores, a dedicated application processor, and a high-efficiency power management unit, thereby laying a solid hardware foundation for sophisticated audio processing and wireless communication functions. Based on this high-performance chip, the FSC-BT1058 module further incorporates an RF front-end, memory components, an audio codec, and a rich suite of interfaces. This integration enables the module to function as a fully-fledged wireless audio subsystem, which can effectively reduce the product development cycle for customers.
