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! https://elecena.pl/product/17502734/sparkfun-qwiic-stemma-qt-hat-for-raspberry-pi 2021-04-07 https://elecena.pl/product/17502734/sparkfun-qwiic-stemma-qt-hat-for-raspberry-pi 2021-11-07
