These Socket Headers alone are, well, lonely. But pair them with the Raspberry Pi Pico, and you're in business!

Socket headers are like the duct tape of electronics. They're great for connecting things, soldering to perf-boards, sockets for wires or break-away header, etc. These particular ones are designed to match up with boards that have two rows of 20 pins, so you can plug things in and out with ease.

Note: Kit includes two 20-pin header.  Pico not included.
