Yibuy 100 Piece Gold Plated PCB Probes Pattern die Part Pin Pogo Pin 1mm Pin Gold-Plated Copper

I bought these and they work great. I am making magnetic electrical connectors and used these to start with. They are springy and easy to fit in. I had to switch to some with a flat surface but if you need to connect above and below, these work great. Might use these to fix my broken UPS hat for my other pi projects. A must buy if you are trying to keep things compact and snappy. Buy it if you need it.

You actually get what you pay for. Bring your glasses cause they're really tiny.

I like using these in my 1:87 scale RC cars for programming and battery charging using tiny neodymium magnets to pull up these contacts to the vehicle. Just drive up to the 1:87 gas pump and the magnet snaps themselves in place for charging.

Micro small there to small for what i'm working on now, but I can use for other things in the future there so small its crazy.. lovm An idea how small they are they are, as big around as my mechanical 00.7 lead pencil end. Going to need a jewelers drill bit as well

Good for test pads, not good for through holes.
