新人试水卡裆了··· #41

看一下是不是短路了吧 |
测一下mipi线吧,我之前也是不亮 |
请问复刻成功了吗,我现在没连屏幕但是按理说充电宝功能应该是可以独立使用的 |
别自己弄了,他那设计的 ic 都是老版本的,现在买的原理图脚位都不一样。直接去买二手成品还便宜 |

我正在做这个神器,电路已经焊好了,电路目测没有明显的问题,但是还是遇到两个问题卡住了:
1.充电宝部分type-C口能充电,USB口能输出5V,但是导电铜柱输出只有2.3V,这是正常的吗?因为没有成功案例参考,不确定哪些现象正常哪些不正常;
2.屏幕部分烧录驱动失败,也不知道是什么问题,如果说这跟问题1有关,那我用其他方式另外给它供电也还是失败的,除了烧录文档上写有的,是还有什么注意事项我遗漏的吗?
当然由于设备和技术等因素,很大的可能性是电路焊接导致的,但是一方面物料没那么充足(已经废了三四套物料了),经不起我随便造,一方面没有成功案例参照(稚晖君本尊的“不算复杂”就不提了),望各位大佬们指教
