This 300 mm (11.8") 4-wire cable is fitted with JST-SH female 4-pin connectors on both ends. The 1 mm pitch JST-SH connectors are more compact than the chunkier 2 mm pitch JST-PH, while still providing a secure latching connection that is easy to insert and remove.
Compatible with both STEMMA QT and Qwiic ecosystems, this cable provides a quick plug-and-play connection for I2C sensors, drivers, and breakout boards. Data wires are interleaved with ground and power to reduce cross-talk.
Key Features
- JST-SH 4-Pin Connectors – 1 mm pitch, female connectors on both ends

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- 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.
- pH
- A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.
- 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.
