The ELECROW Crowtail – I2C Hub 2.0 is an expansion module designed to increase the number of I2C interfaces available on your Crowtail-compatible system. It features four 4-pin I2C ports, allowing you to connect multiple I2C devices simultaneously, each with unique addresses. This is particularly useful when working with sensors or modules that communicate over I2C but have fixed addresses. By using the I2C Hub, you can overcome the limitation of a single I2C bus and manage multiple devices without address conflicts. The module is designed for easy integration, featuring a simple connection to the base shield and providing a straightforward solution for expanding I2C connectivity in your projects.
