SparkFun Qwiic pHAT Extension for Raspberry Pi 400

The SparkFun Qwiic pHAT Extension for the Raspberry Pi 400 provides you with a quick and easy solution to access all of the 400's GPIO, stack your favorite HAT right-side up, or connect a Qwiic-enabled device to the I2C bus (GND, 3.3V, SDA, and SCL). Since the Qwiic system allows for daisy-chaining boards with different addresses, you can also stack as many sensors as you’d like to the mounting holes on the pHAT to create a tower of sensing power!

The Qwiic pHAT Extension connects to the Raspberry Pi 400's GPIO using a 2x20 right angle header and extends out to the edge of the PCB. Two Qwiic connectors are included on each side of the board for easy access to the I2C bus. A set of large silicone bumpers have also been included for better stability when connecting the Qwiic pHAT Extension to the Raspberry Pi 400's GPIO port.

Note: The Raspberry Pi 400 is NOT included. Check the Hookup Accessories section below for Raspberry Pi 400 options.


The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

How to use either Python or C++ to drive the I/O lines on a Raspberry Pi.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

  • This looks like it might also work for the Cooler Master Pi4 case I just received from a Kickstarter campaign, except for the key on the female connector. It's got a metal top that is used as a fanless heatsink and they brought the header out the side of the case rather than penetrating it on top. Looks like the pin assignment orientation is correct.

  • would it be possible to add a vertical female header rather than a right angle one to have the hat facing toward the user?

    • Hi, yeah that's a good question. We went with the horizontal layout that you see because it allows for people to stack their hats without obstructing the keyboard. I can certainly see a use for a vertical extension board but we felt this would capture the desire of more customers than the alternative, though your comment has brought it up again. Perhaps we'll look at offering a number of orientations in the future.

    • Adafruit's equivalent product is oriented that way
