When you all are testing, can you also confirm that the two USB wires are not swapped. Thanks!

I just tested my cable and it is the same issue that caused mine to melt. I sent my board for RMA so I'll respond to that email thread.

FYI it is possible to pull the pins out and swap them, but it weakens the little plastic retaining piece so it is not as solid anymore ... and it makes it confusing since the red is now ground.

I've had almost the exact same thing happen but I think ours got hot enough to desolder a part (see pictures). Feels like a manufacturing issue. Is there a way to send it in for an RMA/replacement/etc?

Here is more info:

We have a FC2.

The FC2 is brand new (purchased within the last couple months).

We did the following:

• connected the USB cable '10' to J3.
• connect a known working micro-usb cable to my laptop running QGC.
• didn't here the usual windows 'new usb device sound'

This was the first time we connected this board. We didn't see any LED's turn on within a second or two so we picked it up by the corners and noticed it was VERY hot.

We quickly disconnected everything.

We inspected the board and found a component on the bottom looks like it shifted off it's solder pads. See attached picture. We didn't inspect the board before hadn

What could have caused this? Especially given a few others have had this.

Thanks!
