nRF5340 Audio DK 低功耗藍牙音訊開發套件

更好的音質、更長的播放時間以及全新功能。

我們的nRF5340音訊開發套件(DK)是「低功耗藍牙音訊(Bluetooth LE Audio)」產品的推薦平臺，它包含開發所需的一切。此套件可進行設定，並作為USB收發器傳送或接收來自PC的音訊資料。它也可以用於辦公耳麥或真無線立體聲(TWS)耳機。對於大多數應用，我們建議使用兩個或以上開發套件。

主機板元件

這款開發套件的三個主要元件分別是nRF5340 SoC、nPM1100 PMIC和Cirrus Logic的CS47L63音訊DSP。CS47L63的高效能DAC和差分輸出驅動器經過最佳化，可直接連接至外部耳機負載。它非常適用於擁有僅單聲道和直接揚聲器輸出的耳機。

開發套件供電

nRF5340音訊開發套件採用USB供電。可以使用專用的電流測量接腳測量電流消耗情況。我們建議使用Nordic的Power Profiler Kit II進行電流測量。

全新編解碼器

這款開發套件還加入了全新的「低複雜度通訊編解碼器」(LC3)，其取代了經典藍牙的「低複雜度子帶編解碼器」(SBC)。與SBC相比，即使在大約一半的無線資料速率下，LC3編解碼器仍具有優秀的音訊質量。這種低資料速率是降低產品功耗的關鍵。
