It's a cable and fits an Adafruit LTC4311
I bought this along with an Adafruit LTC4311 I2C extender. I cut it in half to use in my project. This was the easiest way to connect the LTC4311.

This 4-wire cable is a little over 200mm / 7.8" long and fitted with JST-SH female 4-pin connectors on both ends. Compared with the chunkier JST-PH these are 1mm pitch instead of 2mm, but still have a nice latching feel, while being easy to insert and remove.
This cable can be used with Qwiic or STEMMA QT boards, to easily connect sensors and drivers from one board to the other. The cables are made symmetrically so don't worry about which side goes where!
The colors are:
- 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.
- 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.
- SCL
- The clock line used by the I2C bus to keep data transfers timed between a controller and connected devices. When wiring I2C, SCL must be connected to the SCL pin on every device sharing the bus.
- SDA
- The data line used by the I2C bus to carry information between a controller and connected devices. When wiring I2C, SDA must be connected to the SDA pin on every device sharing the bus.
- 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.
