请教坛子里10元买的千兆AP主板上有没有5V供电

threedollars

看了下，该主板应该有不少坛友买了，原贴子是：https://www.anywlan.com/thread-438633-1-2.html，上有主板图片。

要上QCA9880，需要独立的5V供电，这个板子不知道在哪里能找到5V供电的点位，请教请教。
固件编译过程中，LEDE-17.01.7有ath10k支持。

LEDE-17.01.07 SFE固件编译好了。可惜不知道在哪里可以引入5V供电。

君悦HDCD

你在板子上现在加的电压是多少 ？

threedollars

12伏电源

这不太简单了，用万用表挨个找找，实在找不到5v,飞线3.3v过去也可以,明天不忙我给找找看看

3.3V也可以么？PCIE接口上应该有3.3v的吧

threedollars

在主板上找了下，有3.6V的电位点。焊了根导线，和QCA9880上的5V点位连接起来，就可以使用了。

3.3V也可以么？PCIE接口上应该有3.3v的吧

3.3v以上都可以,5V可以达到最大功率输出，3.3v以上虽然达不到最大，但依然效果可以

干的不错，推荐网友学习
