nRF5340 Audio DK低功耗蓝牙音频开发套件

更好的音质、更长的播放时间以及全新功能。

我们的nRF5340音频开发套件(DK)是“低功耗蓝牙音频(Bluetooth LE Audio)”产品的推荐平台,它包含开发所需的一切。此套件可进行配置,并作为USB收发器发送或接收来自PC的音频数据。它也可以用于办公耳麦或真无线立体声 (TWS)耳机。对于大多数应用,我们建议使用两个或以上开发套件。

主板组件

这款开发套件的三个主要组件分别是nRF5340 SoCnPM1100 PMIC和Cirrus Logic的CS47L63音频DSP。CS47L63的高性能DAC和差分输出驱动器经过优化,可直接连接至外部耳机负载。它非常适用于拥有仅单声道和直接扬声器输出的耳机。

开发套件供电

nRF5340音频开发套件采用USB供电,并配置一个电池。可以使用专用的电流测量管脚测量电流消耗情况。我们建议使用Nordic的Power Profiler Kit II进行电流测量。

全新编解码器

这款开发套件还加入了全新的“低复杂度通信编解码器”(LC3),其取代了经典蓝牙的“低复杂度子带编解码器”(SBC)。与SBC相比,即使在大约一半的无线数据速率下,LC3编解码器仍具有优秀的音频质量。这种低数据速率是降低产品功耗的关键。
