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.
- Black for GND
- Red for V+ - For Qwiic boards, 3.3V. For STEMMA QT, 3 to 5V.
- Blue for SDA
- Yellow for SCL

Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
