宝贝介绍
orange pi pc plus 开发板，有内存芯片撬坏了，板应该是报废了，板上BGA焊盘都掉了。只能拆芯片片了。其他芯片应该还是好的，反正撬之前是可以用的，我手贱，想把散热片撬下来，结果把内存芯片给撬下来了。。

品牌 香橙派
成色 轻微使用痕迹

看描述，反正撬之前是可以用的，只是eMMC芯片和焊盘挂了，我看了板子背面还有TF卡可以抢救，如果抢救失败就当35元扔水里面了。

板子收到， 还不错，带外壳，可惜没电源。

一狠心剪了一根绿联的USB线，直接焊上， 基本OK， 可以进入FEL模式，正在下载固件。

貌似这个主线uboot的卡兼容性不好引起的，换一张卡就OK了：

致敬，有手艺 有功底 才敢捡漏！

接个垃圾堆里面的15寸屏试一试。

量了一下，手里面两根线都是 地 / 黄 / 白 / 红 的顺序，对照香橙派的原理图，应该是可以用的。

发现OpenWRT已经内置了Orange Pi PC 支持了。
