Dear all

FP2 Bottom Module: Repair broken µUSB port

@JohnHughes (thanks again) send me two broken bottom Modules some days ago. This one has a defekt µUSB port. After disassembling I took a picture with a microscope camera and found some solder cracks. Barely to see without magnification.

I will try to resolder the joints and hope the bottom module will be able to do its work…

Also @Leo_TheCrafter is likely able to tell you which and where the mics are sourced from. I presume you have seen Leo’s module making posts. Look them up if not
