SparkFun Qwiic pHAT v2.0 for Raspberry Pi - STEMMA QT / Qwiic

Product ID: 5142


The SparkFun Qwiic pHAT V2.0 for Raspberry Pi provides you with the quickest and easiest way to enter into SparkFun’s Qwiic or STEMMA QT ecosystem while still using that Raspberry Pi that you’ve come to know and love. The Qwiic pHAT connects the I2C bus (GND, 3.3V, SDA, and SCL) on your Raspberry Pi to an array of Qwiic/QT connectors on the HAT. Since this system allows for daisy-chaining boards with different addresses, you can plug in as many sensors as you’d like!

The Qwiic pHAT v2.0 has four Qwiic connect ports (two on its side and two vertical), all on the same I2C bus. SparkFun also made sure to add a simple 5V screw terminal to power boards that may need more than 3.3V and a general-purpose button (with the option to shut down the Pi with a script). Also updated, the mounting holes found on the board are now spaced to accommodate the typical STEMMA QT / Qwiic board dimension of 1.0" x 1.0". This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header as well as the NVIDIA Jetson Nano and Google Coral.

Note: When placing a Raspberry Pi and the pHAT in an enclosure (with the enclosure top attached), SparkFun notes that that the pHAT may not be fully inserted in Pi's header pins. For a secure connection, you'll need to add a riser header.


  • 4x STEMMA QT / Qwiic Connection Ports
