上图放大区底、面部接线。

注意指示发光二极管要用论坛供应小型的一种，否则亮度会较暗。

还是用晶体管较好，

以下是引用stanleyjin在2005-12-8 13:05:00的发言：
可不用PNP管，直接从8414的pin28接LED和1K电阻到+5V。

对CS8412比较安全！

另：最早期的1543也可以这样加装信号指出灯。

我比较喜欢电平指示的

俺早就加了

电路图中晶体管已更正，

晶体管一般用小型PNP硅管大致都可代替。

更正：第一图片中"单枝粗粗线"是"单枝粗铜线"之误。

图中三极管PNP画成NPN的了....

下山虎 发表于 2005-12-8 09:03

三极管用那些型号可以代换？？？
