Different from our Grove system, Qwiic is an I2C interface system initiated by Sparkfun around 2017, using a 4pin JST SH 1.0mm connector. STEMMA QT initiated by Adafruit is cross-compatible with Qwiic, as they use the same connector/cable. To better support different types of interface systems, we provide Grove – Qwiic Hub, which enables you easily connect the I2C devices with Grove/Qwiic/STEMMA QT interface, get the best use of your devices/controller of different interfaces.
Grove – Qwiic Hub allows you to either use Qwiic/STEMMA QT modules on Grove controller or use Grove modules on Qwiic/STEMMA QT controller. You can cascade connect more than one Qwiic/STEMMA QT and Grove modules in one I2C bus with Grove – Qwiic Hub. It also has a built-in level shifting function that allows 3.3V/5V supply voltage.
