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.
