This compact breakout adds a 4-pin JST SH connector to a Raspberry Pi or compatible board, giving you a quick STEMMA QT/Qwiic connection for I2C sensors and devices. The 2x3 socket plugs onto the Pi’s I2C and power pins with no soldering required, so it is easy to fit and remove when you need it.
The board connects to SDA, SCL, 3V and Ground, and includes a 3.3V regulator to help power STEMMA QT and Qwiic devices without causing a brownout dip. A green power LED shows when it is powered correctly, and two 10K pull-up resistors are included for Pi-compatible boards that do not already provide them.
It can also be used with Linux single board computers or microcontrollers that have a 2x20 Pi-compatible pinout. For software, Adafruit’s Blinka Python interface library lets you use many CircuitPython libraries on SBC computers from Python.
Features:
- STEMMA QT/Qwiic connector: Adds a 4-pin JST SH connector for quick I2C device connection.
- No soldering required: 2x3 socket plugs directly onto the Raspberry Pi I2C bus pins.
- Pi-compatible pinout: Works with Raspberry Pi and compatible boards using a 2x20 Pi-compatible header.
- I2C connections: Breaks out SDA, SCL, 3V and Ground.
- 3.3V regulator: Helps power Qwiic or STEMMA QT devices without risking a brownout dip.
- Power indicator: Green LED shows the board is powered correctly.
- Pull-up resistors: Includes two 10K pull-up resistors for compatible boards that need them.
- Blinka support: Compatible with Adafruit Blinka for using CircuitPython libraries on SBC computers with Python.
Specifications:
- Product Dimensions: 15.2mm x 15.0mm x 5.5mm / 0.6" x 0.6" x 0.2"
- Product Weight: 1.1g / 0.0oz
Ideal for quickly adding I2C sensors, displays and other STEMMA QT or Qwiic devices to Raspberry Pi projects without header fiddling.
Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- 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.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- 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.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- 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.
