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.
