1,这个用风枪吹一下,很容易焊好噢。。那个JTAG座旁边的电阻确实要补上。。通常接472(4.7K)贴片电阻。
2,最下面9针是RS232串口,可以弄条TTL线接上看看输出信息。。
其实这个机器很容易就活的。。JTAG,TTL都有 ...

别人有,不如自己有。邮来邮去的费时费钱。

谢谢你的热心。

多谢夸奖,在这之前基本没焊过东西。


1,这个用风枪吹一下,很容易焊好噢。。那个JTAG座旁边的电阻确实要补上。。通常接472(4.7K)贴片电阻。

抱歉,我只有个小电焊。电阻阻值要求必需精确吗?有点难找啊


2,最下面9针是RS232串口,可以弄条TTL线接上看看输出信息。。

边上有空位,是不是需要补什么元件。TTL如何接啊?

唉,之前看到过老外标注的TTL图,没留意,等需要的时候却找不到了。。。

真不容易,翻出个废主板,找半天,焊下4个4.7K,2个5.4K。

请问高人,5.4K能否使用?

应该4个就够用,下步找有风枪的焊上。
