这个做法非常非常奇怪，后边一根完好的Uusb线插电脑已装好驱动还从那里取电，不闻不问从板子左右又接出一个usb头插回电脑里
果断买材料做啊

没问题了原来是 那个 添加库 的问题 我是 MINI用TTL 的接5VGNDRX DX要怎么改》
请教楼主，该方法在widows系统下没问题。但是windows启动前比如想自动输入Bios密码时没反应，而一般的usb键盘可以。请问有办法在windows启动前也能用吗？
我可以用USB 转TTL 的线做么？
想试试看，我的UNO可以做吗？

想试试看，我的UNO可以做吗？
当然可以.如果有3.3V的电池(磷酸铁锂)或两个1.5V的干电池串起来做电源,就只需要一个2.2K(或1.5K)的电阻.

没有合适的稳压管, 不过仔细看看,稳压管是电平转换用的,只要电平合适不用也可.思路有两个
1.用3.3V的铁锂供电,(USB口vcc悬空),如视频,除UNO和USB公头,必要的杜邦线外,只有一个2.2K电阻,顺利实现windows开机密码输入
2. USB口引出5V,1117,317等IC稳压到3.3给UNO供电,这个还没试验.
弱弱的问一句↑↓←→，shift,ctrl,alt是哪几个？

出现这样的错误，怎么解决？？
成功了。但是焊接的时候根据你的焊点焊的，貌似有问题，后来根据电路图焊接就对了。你的焊点绿白貌似反了
看起来很棒，做一个试试:lol
