The Pogo Pin Probe Clip with 6 pins in a 2.54 / 0.1" pitch 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 0.1" spaced 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 extended up into a 1x6 0.1" header for everyday socket header cables to plug into. You can use these cables to extend out to your programmer or adapter.
