The SparkFun Qwiic pHAT Extension for Raspberry Pi 400 provides access to the Pi 400's GPIO header while adding Qwiic I2C connectivity. The board connects via a 2×20 right-angle header and extends out to the edge of the PCB, allowing you to stack HATs right-side up or connect Qwiic-enabled I2C devices.
Two Qwiic connectors (one on each side) provide easy access to the I2C bus (GND, 3.3 V, SDA, SCL), with support for daisy-chaining multiple Qwiic boards. Silicone bumpers are included for stability when connected to the Pi 400's GPIO port.
Key Features
- Full GPIO Access – 2×20 right-angle header extends all Pi 400 GPIO pins
- Dual Qwiic Connectors – One on each side for convenient I2C device connection
- HAT Stackable – Mount standard Raspberry Pi HATs right-side up
- Daisy-Chain Support – Connect multiple Qwiic I2C devices in series
- Silicone Bumpers – Included for stability on the Pi 400
Specifications
- Connector – 2×20 right-angle GPIO header
- Qwiic Ports – 2× JST-SH 4-pin (1 mm pitch)
- I2C Bus – GND, 3.3 V, SDA, SCL

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.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- 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.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- pHAT
- A smaller add-on board format for Raspberry Pi, similar in idea to a HAT but usually not full-sized. It matters because pHAT compatibility can affect how neatly a board stacks or fits into a Raspberry Pi project.
- 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.
