[Ovmsdev] USB port fragility

[Mark Webb-Johnson]

The small solder area is my suspicion too, and a relatively easy fix. Through hole would be better but would require a new component and circuit redesign (with associated complexity and re-certification issues). Here are some pictures of the 2020-06-15 batch with the changes. But it will be some time before distribution stock is cleared out and those start to be shipped. Note also that 2020-06-15 also includes a change to new thicker antenna cables for both GPS and GSM.

Regards, Mark.

When I took it apart I could see that there was not very much solder in the four holes that secure the usb shell to the board. At the time my suspicion was that the small amount of solder from the factory wave solder made for a weak bond. I was lucky that I didn't lift any pads and was able to resolder it.
