八、设计注意事项: (模块兼容 8610,8620,8640,8645 四个 IC,就是分单,双声道)
1) BC8610,8620---------------是单声道的芯片 这时音频只有 PIN41,PIN42 也就是 SPK_L_N, SPK_L_P 有音频输出,而 SPK_R_N, SPK_R_P 是空脚 ------------------------------------------------------------------------------------------------------------------------BC8640,8645---------------是双声道的芯片,SPK_L_N, SPK_L_P,SPK_R_N, SPK_R_P 都有音频输出,属于立体声 2)IO 口注意事项 PIO21,PIO20,PIO19,PIO18,PIO7,只有这 5 个 IO 口可以用来做按键,其他的口做输出。 --------------------------------------------------------------------------------------------------------------------------

九、电路连接注意:
F-3188 外接功放的时候,必须接差分输入的功放,如果不接差分输入的功放,必须接一个运放 平衡两个差分的电平,否则会有“啪啪”的冲击声。

十、注意事项:
A.关于无线蓝牙的使用环境,无线信号包括蓝牙应用都受周围环境的影响很大,如 树木、金属等障碍物会对无线信号有一定的吸收,从而在实际应用中,数据传输的距离 受一定的影响。 B.由于蓝牙模块都要配套现有的系统,放置在外壳中。由于金属外壳对无线射频信 号是有屏蔽作用的。所以建议不要安装在金属外壳中。 C.PCB 布板:蓝牙模块的天线部分的是 PCB 天线,由于金属会削弱天线的功能,在给模 块布板的时候,模块天线下面严禁铺地和走线,若能挖空更好。
