Designing boards with plug-n-play connectivity is a snap, with STEMMA connectors. Here's a pack of 10 of our favorite 2mm pitch connector - the JST PH 3 pin. These are the horizontal style.
You can use these with any of our JST PH 3 / STEMMA cables. They're not STEMMA QT compatible (those use the smaller JST SH).
We also carry these connectors in vertical style.

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.
- JST PH
- A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.
- 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.
- 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.
