我的TDA1543纪念版

文招

首先用数字表量电阻，每量一个就插一个在PCB对应位置上，这样不容易搞错。全部电阻都插完后在PCB底部把电阻引脚向两边弯开，这样电阻就紧贴在PCB上定位了。然后在上部焊接，焊完全部电阻后就可在底部剪引脚了，电阻脚留2mm左右长，再在底部焊接，其实底部不焊也可以，但焊后更美观，也更可靠。

焊前看清楚PCB与线图原理, 焊后不急着立即通电, 总会小心核对数次.

全连就是外部时钟!

SAGAQWE

全开路时便是使用8412的内部时钟.
接线没错呢, 只是这样须悭了一个4位SW的使用, 却少了可比较内/外部时钟的玩法.

文招

也就是说，我现在用的是本板上的时钟？现在的开关三条短路线没接错吧？[em11][em11]

不用了，寄来麻烦的说。我还是短接算了，但就是求SW4的脚定义

我这儿有，SW4---SW10的都有，就是要回头找
