Frankly, I do not like those tiny USB connectors..
So after maybe 10 insertions in total the usb socket casing's fin broke off the pad - after a re-soldering and subsequent insertion the pad copper broke off the pcb..
The usb socket casing solder pad is something like 1x1mm large on this board..
As I like the module I decided to save its life somehow fast - the first aid I have applied is similar to a front line surgery, however
I cleaned up the pcb around the pads and put larger tin blobs to fasten the socket casing firmly to the copper.
I fired up the module and burned my finger.. NOT a good idea..
After some studying the pcb layout in the Eagle I recognized the upper fill is actually +3.3V so I shortened it against GND.
Thus I decided to cut the the 3.3V parts off the socket casing pads - see the final cuts below - two on the top, and one on the bottom side.
Now it works somehow
again..
