A 200mm adapter cable with a JST-SH 4-pin connector (STEMMA QT / Qwiic, 1mm pitch) on one end and a JST-PH 4-pin connector (STEMMA / Grove, 2mm pitch) on the other. Use it to bridge I2C sensors and drivers between the two connector ecosystems.
Both connectors have a latching feel for secure connections while remaining easy to insert and remove. The cable works with boards like PyPortal, PyBadge, PyGamer, HalloWing, and any other device with a 4-pin JST-PH or JST-SH I2C connector.
Key Features

- 1× JST-PH to JST-SH 4-pin cable (200mm)
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 2mm pitch
- Pitch is the distance between the centres of neighbouring pins on a connector. A 2mm pitch header is smaller than the common 2.54mm breadboard spacing, so you need matching cables and headers rather than standard breadboard jumper leads.
- Grove
- Grove is a plug-in connector ecosystem for sensors and modules that avoids soldering and jumper wires. Grove compatibility matters because it can make it quicker to add supported I2C devices, as long as the cable and voltage are suitable.
- 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.
