Summary

6-channel I2C hub enabling multiple Grove I2C devices to share a single bus with individual channel selection.

Description

The M5Stack I2C Hub component is a 6-channel I2C switch based on TCA9548A that allows up to 6 Grove I2C devices to share a single I2C bus. Each Grove port can be individually selected and controlled, preventing address conflicts and enabling efficient bus management. The hub features low standby current, power-on reset function, and supports both standard and fast mode I2C protocols. Designed specifically for M5Stack ecosystem with Grove connectors. Typical applications include multi-sensor systems, display multiplexing, and complex I2C bus architectures in modular systems.
