This cable will make it super easy to use our plug-and-play STEMMA QT boards and controllers with chips, breakouts, and other devices that are I2C compatible but don't come with a STEMMA QT socket already on 'em.

On one end you get a Qwiic / STEMMA QT connector (technically known as a JST SH 4-pin plug)  into 4 individual wires with 'micro hook' ends. The hooks are much finer pitch than our alligator clip QT cable, and can easily grab on to through-holes, wires, DIP, or SOIC/SOP chips. These are not small enough for TSSOP's or TQFPs. If you need to add test points, we stock through-hole ones that fit nicely into 0.1" holes

Please note - These hooks are not the high-quality ones you see that come with expensive logic analyzers - but they do get the job done!

This cable has a JST SH 4-pin on one side and micro hook clips on the other.
