I have a Pro Micro board (very small -- see pic below) and it has connector holes in the printed circuit board. If you’ve ever struggled to solder a thick circuit board trace or TO220 package with a soldering iron, you’ll understand the problem. I think I need to re-solder them back (I know what wire goes where, I don't need help for that). Note that these two wires have been soldered together. hand soldering basic is done during PCB rework in a production unit when a smartphone PCB gets smash crash damage. This allows you to find any mistakes or bugs that you've missed.
