A 10-pack of JST SH 4-pin vertical connectors with 1 mm pitch through-hole mounting tabs. These micro connectors are compatible with the Qwiic/STEMMA QT ecosystem, making them perfect for adding I²C connectivity to custom PCBs.
The solid plastic housings feature through-hole pins that can also be used in SMT reflow — simply paste over the through-holes and the pads will solder in place.
Key Features
- JST SH Series – 1 mm pitch, 4-pin vertical connector
- Qwiic/STEMMA QT Compatible – Works with standard Qwiic cables and boards
- Through-Hole Mounting – Also compatible with SMT reflow soldering
- Quantity: 10 connectors per pack
Qwiic Pinout
- Pin 1: GND (black wire)
- Pin 2: 3.3 V (red wire)
- Pin 3: SDA (blue wire)
- Pin 4: SCL (yellow wire)
Tip: Qwiic cables are wired symmetrically, so either end can be plugged in to either connector.
Ideal For
- Adding Qwiic/STEMMA QT connectors to custom PCBs
- I²C sensor and driver breakout boards
- Prototyping with modular I²C connections
Package Contents
- 10× JST SH 4-pin vertical connectors
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- 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.
- 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.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
