If you love power adapters or toys & gadgets that have magnetic connections, you can now experiment with these futuristic connectors easily. It's sorta like a DIY "MagSafe-styled" connector, with seven 2.2mm spaced contact pogo pins and a straight solderable connection to your PCB. If you've ever owned a MacBook or a littleBits set, you'll find the functionality familiar. This pitch is too small for standard breadboarding.
Bring the two halves together and the embedded magnets attract, making a firm connection and assuring that all the pogos make contact. If you try to connect the contacts backward, they will repel!
Use it for power, data, and maybe a magnetic STEMMA QT or USB connector? - whatever you wish! Comes with two halves that, of course, match up nicely.
