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。

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

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
