蓝牙音频模块说明文档V1.3（5V）

蓝牙音频模块说明文档V1.3（5V）蓝牙音频模块说明文档(5V)一、外观实际产品，已经焊接了插针，默认为90度弯针二、端口说明：1、+5V 电源：接电源正极，电压范围4.2V~5V ，请确保供电在此范围内，超这个范围可能损坏模块，或者导致工作不正常；2、地：GDN 接电源负极，也是音频的地，此地必需分开两根地线分别接电源地跟音频地；3、左声道：接功放板左声道输入，或者耳机的左声道，建议在该输出端口接入一个电容(视功放所匹配的输入而定)；4、右声道：接功放板右声道输入，或者耳机的右声道，建议在该输出端口接入一个电容(视功放所匹配的输入而定)；5、静音输出端口：该端口预置为高电平，当静音时该端口输出低电平；6、状态指示灯：当蓝牙未连接时，该灯快闪，一旦蓝牙连接成功则变为慢闪；7、预留端口：该端口已经上拉到5V ，当该端口给一个低电平触发后关机，当再次给该端口一个低电平复开机。

系统典型接线图：注意：从蓝牙音频模块到电源或者到音频接口，请采用焊接的方式，不要采用插线的方式，接触电阻比较大会引入噪声。

三、使用注意事项：1、供电电源：蓝牙音频模块属于对高频干扰敏感的电路，建议采用线性稳压电源，若采用DC-DC供电时，请加入LC滤波，降低电源谐波干扰，尤其采用手机充电器等开关电源，电源纹波可能致使蓝牙不能正常连接，而且这类的5V输出，往往在5.1V~5.4V之间，超过了蓝牙音频模块的工作电压；当采用手机适配器等开关电源工作时，请加这个供电电路，电感可不加。

2、接地：由于音频信号对于接地点引起的干扰比较敏感，可以在蓝牙模块的输出插针上面焊两根地结，一根接到电源的负极(GND)，另外一根接到功放板的音频输入地，尽量焊在线路板上，不要采用引线接连(容易受干扰)，并且建议可以多试一下那个接地点干扰最小；3、天线干扰：蓝牙天线极其容易受到高频，或者强电磁信号干扰，相对来说尽量远离功放板的强信号的地方，并且天线不能紧挨着金属物品，保持一定的距离；4、外壳屏蔽：由于金属外壳的机壳对于蓝牙信号有屏蔽作用，可能衰减蓝牙信号致使接收不良，请保持在有相应的开孔，或者外露。

蓝牙模块使用说明一、模块简介：1、芯片简介该蓝牙模块采用台湾胜普科技有限公司的BMX-02X模块为核心，它采用CSR BLUEcore4-External芯片并配置8Mbit的软件存储空间，成本低，使用方便。

CSR BlueCore4是英国Cambridge Silicon Radio(CSR)公司日前推出的第四代蓝牙硅芯片。

这种硅芯片用于蓝牙技术推广小组(SIG)推出的增强数据传输率(EDR)蓝牙。

CSR的BlueCore4的数据传输率将比现有的v 1.2蓝牙装置快三倍，并且使蓝牙移动电话或手机的耗电量较低。

蓝牙EDR的最大数据传输率为每秒2.1兆比特，而目前v1.2标准传输率则为每秒721千比特。

传输率的提高意味着对一个特定量的数据来说，EDR无线电的工作将比v1.2无线电快三倍，从而减少耗电量，大大有利于依赖蓄电池的移动设备。

CSR BlueCore4完全能与现有蓝牙v1.1和v1.2装置兼容。

蓝牙EDR用一种相移键控(PSK)调制模式取代标准传输率的Gaussian频移键控(GFSK)，实现更高的数据传输率。

CSR BlueCore4正在以两种形式提供——一种用于外部“快闪”存储器，一种用于掩模ROM。

BlueCore4-External以一种8×8mm BGA(球形格栅矩阵)封装提供，是十分灵活的解决方案，能够适应迅速更新的市场。

例如，由于BlueCore是目前可以得到的唯一能够支持蓝牙v1.2规格的所有强制和可选功能的硅芯片，BlueCore4-External为PC应用程序提供了理想的解决方案，使它们得益于以三倍速度的传输率无线传输文件，或者同时操作多个高需求的蓝牙链路。

鉴于蓝牙固件安装在芯片只读存储器上，CSR BlueCore4-ROM 的成本较低，占用面积小得多(在小片尺寸包装中为3.8×4mm，在与BC2-ROM和BC3-ROM引脚兼容的BGA中为6×6mm)。
