The SparkFun Qwiic HAT for Raspberry Pi is the quickest and easiest way to enter SparkFun’s Qwiic / STEMMA QT ecosystem when using that Raspberry Pi that you’ve come to know and love. The Qwiic HAT connects the I2C bus (GND, 3.3V, SDA, and SCL) on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy-chaining boards with different addresses, you can stack as many sensors as you’d like to create a monolith of sensing power!
The Pi HAT has four (count ‘em, FOUR!) Qwiic connect ports, all on the same I2C bus. In addition, many of the useful GPIO pins on the Raspberry Pi are broken out. This HAT is compatible with any Raspberry Pi or single-board computer with a standard 2×20 GPIO header.
