Recycled Keychains

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.
