DJI Mini 2 Drone Teardown Analysis
这篇摘要总结了作者对使用四年的DJI Mini 2无人机进行拆解和问题分析的全过程,字数控制在200字以内。 --- 一篇关于大疆Mini 2无人机的拆解分析文章。作者因无人机5.8GHz图传信号变弱,在过保后决定自行拆机维修。文章详细记录了拆解步骤,并对关键芯片进行了技术分析:主控采用NXP的i.MX RT1064处理器;图像处理由安霸Ambarella H22芯片负责;图传系统核心为DJI定制的S1系列芯片,并由QPF4205和QPF4550分别放大2.4GHz和5.8GHz信号(怀疑故障源于后者);此外,还解析了电机驱动、电源管理及ToF测距等模块的芯片配置与功能。此次拆解旨在排查并更换故障的5.8G功放芯片,修复图传问题。
