The Pogo Pin Probe Clip with 2x5 0.05" pitch SWD spacing is a great way to test and connect with pin-point accuracy without soldering! It's sort of like an alligator clip with an array of built-in springy pogo pins - so you can connect to a PCB with classic 'SWD' pad holes, without soldering or a special adapter cable.

The clip is constructed from PCB sections, with a sandwich to support the thin pogo pins. The pogos are then duplicated into a 2x5 0.1" header for everyday socket header cables to plug into. You can use these cables to extend out to your programmer or adapter.
