SparkFun Qwiic pHAT Extension for Raspberry Pi 400

The SparkFun Qwiic pHAT Extension for Raspberry Pi 400 is a convenient tool that allows easy access to all of the 400's GPIO. It enables you to stack your preferred HAT right-side up or connect a Qwiic-enabled device to the I²C bus (GND, 3.3V, SDA, and SCL). The Qwiic system's unique feature is the ability to daisy-chain boards with different addresses, which means you can stack as many sensors as you want on the pHAT's mounting holes, creating a powerful sensing tower.

The Qwiic pHAT Extension connects to the Raspberry Pi 400's GPIO through a 2x20 right angle header, extending to the PCB's edge. For easy access to the I²C bus, two Qwiic connectors are included on each side of the board. To ensure stability when connecting the Qwiic pHAT Extension to the Raspberry Pi 400's GPIO port, a set of large silicone bumpers is also included.

Please note that the Raspberry Pi 400 is not included. For Raspberry Pi 400 options, please check the Hookup Accessories section.

The SparkFun Qwiic Connect System is an I²C sensors, actuators, shields, and cables ecosystem designed to make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, reducing the required PCB space. The polarized connections mean you can't connect it incorrectly.

The SparkFun Qwiic pHAT Extension package includes one Qwiic pHAT Extension for Raspberry Pi 400 and four tall silicone bumpers. It features two Qwiic connection ports and ten mounting holes. It reroutes and extends a Raspberry Pi 400's 40-pin headers to a vertical position.
