I purchased one a while ago, to be able to test doing apps directly on Zephyr...
The board always had issues from the start that sometimes it would program properly and other times fail. Sometimes got better when would wiggle the cable, other times when I pressed my fingers on the connector itself... I suspected that the USB connector probably had issues like colder solder joint or the like.
Well today as I suspected the USB connector broke free from the board...
Probably won't order another, as I only wanted it to develop/test out functionality on Zephyr and ArduinoCore-zephyr...
If it was cold solder joints, you would be able to solder it back in place. The board was made with lead-free solder and perhaps did not have enough flux when soldered. Rough handling is more likely if the connector finally broke free.
Thanks and Yep - probably too rough. But after several attempts to
remove/insert pressure, it came away and unfortunately took away
most/all of the traces.
