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 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.
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.
