What to do with a dead Pro Micro?I use a lot of Pro Micros. They are cheaply made and have a high failure rate. About 1 in 10 are DOA or have some kind of defect. (I have yet to have a genuine Teensy fail, and I have used dozens of them.)
Used some brass wire to make a loop and soldered it in place. Sanded the bottom down so that the copper layer is exposed.
|Half the ports on this one are dead. Stuck in the on position. The USB connector is also crooked.|
|Place the sandpaper on a flat surface and sand against it lightly, just enough to remove the solder mask.|
|I have a lot of these 6 key PCBs. A little large for a keychain.|
