Different from our Grove system, Qwiic is an I2C interface system initiated by Sparkfun around 2017, using a 4pin JST SH 1.0 mm 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.

What is Grove?
Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Not only are these open hardware, but we also have open-source software.
