The Gravity: I2C HUB module allows you to connect up to 8 I2C devices to a single microcontroller, making it easy to build complex sensor networks or project systems. Whether you're using multiple sensors, displays, or modules, this hub simplifies wiring and expands your project's potential without additional coding or address conflicts.
It’s fully compatible with the Gravity series and can be connected via a Gravity-4P I2C/UART sensor cable or standard jumper wires. Ideal for prototyping, classroom learning, or building multifunctional IoT projects.

Example Project
Making an Alarm Clock That Asks Questions Randomly
Combine the I2C HUB with modules like the speech synthesis and recognition units to create an interactive alarm clock. The clock will randomly ask a question and only stop ringing once the correct answer is given—otherwise, it keeps buzzing. A fun way to start your day!
