style="text-indent:25px">那么藍牙模塊到底是什么呢？藍牙模塊是一種集成藍牙功能的PCBA板，主要用于無線網(wǎng)絡通訊，按功能可分為藍牙數(shù)據(jù)模塊（HY-40R201P、HY-40R204P）和藍牙語音模塊。主要由芯片、PCB板、外圍器件構(gòu)成（一般模塊具有半成品的屬性，是在芯片的基礎上進行加工。換言之，藍牙模塊一般具有二次開發(fā)的特性）。如：HY-40R204P藍牙模塊則是基于TI CC2640R2F 藍牙芯片，同時PCB板集成2.4G的PCB天線。藍牙模塊的作用簡單來說就是以無線連接取代有線連接，將固定和移動信息設備組成個人局域網(wǎng)，實現(xiàn)設備之間低成本的無線互連通信。常州大眾藍牙模塊商家</p></p><br /><p>文章來源地址:
