Fixed a dead Arduino Micro Clone
One of the
three pack of Arduino Micro clones I purchased was DOA. I could program it via ISP but it was never recognized over USB.
Upon close inspection two sides of the AtMega32U4 looked to have bad solder connections.
This side doesn't look too bad, but they are the pins that are the USB data pins look a little funny.
There are three pins on this side that don't have any solder at all.
I used a lot of liquid flux and added a tiny amount of solder and rolled it across the pins. Much like in this
video, but I used liquid flux which is much messier.
All pins are now connected with an even amount of solder. I touched up the solder on all four sides.
The Arduino Micro clone now works like it should.
